nan pwogram sa a Seza

ke mwen prezante, ki
nou ap ale nan jwenn deyò.

Barfoo nan tout kaskèt, ak pou kèk rezon

men dezyèm lèt la
Yon rete chanje.

261
00:11:03,980 --> 00:11:07,120
Se konsa, nou ap ale nan eseye ak
konpwan poukisa se sa ki.

262
00:11:07,120 --> 00:11:10,440
Se konsa, premye bagay la ou tipikman
vle fè nenpòt lè ou kòmanse sou gdb

263
00:11:10,440 --> 00:11:12,010
se konnen ki kote yo kraze li.

00:11:16,330 --> 00:11:18,520
Ki sa ki fonksyon nou yo nan Seza tande kòz te ye?

267

268
00:11:19,590 --> 00:11:24,350

269
00:11:24,350 --> 00:11:26,490
Main se yon fonksyon
pou tout pwogram ou yo.

270
00:11:26,490 --> 00:11:29,230
Si ou pa t 'gen Main, mwen ta ka
gen yon ti kras enkyete kounye a,

271
00:11:29,230 --> 00:11:31,000
men mwen espere ou tout te gen Main nan la.

272
00:11:31,000 --> 00:11:34,150
Se konsa, sa nou kapab fè se nou ka
jis kraze Main, jis tankou sa.

273
00:11:34,150 --> 00:11:35,190
Se konsa, li di, OK.

274
00:11:35,190 --> 00:11:37,430
Nou mete yon sèl breakpoint nou an la.

275
00:11:37,430 --> 00:11:42,870
>> Se konsa, kounye a bagay ki sonje se Seza tande kòz
pran yon sèl lòd liy agiman dwat

epi nou pa te fè ke nenpòt kote ankò.

277
00:11:45,150 --> 00:11:47,560
Se konsa, sa w ap fè se lè
ou aktyèlman ale nan kouri

278
00:11:47,560 --> 00:11:51,540
pwogram nan, nenpòt pwogram ke w ap
kouri nan gdb ki bezwen liy lòd

279
00:11:51,540 --> 00:11:55,010
agiman, w ap ale nan D '
lè w ou fèk kòmanse kouri li.

280
00:11:55,010 --> 00:11:59,280
Se konsa, nan ka sa a, nou fè
Kouri ak yon kle nan twa.

281
00:11:59,280 --> 00:12:00,770

282
00:12:00,770 --> 00:12:02,040

ki dosye ke mwen voye moute

285
00:12:12,210 --> 00:12:15,100
ou ap wè ke sa a, se renmen an
premye liy fonksyon prensipal nou an, dwa?

286
00:12:15,100 --> 00:12:17,890
Li nan tcheke yo wè si nou gen
Nimewo ki kòrèk la nan agiman.

287
00:12:17,890 --> 00:12:20,620
Se konsa, si w ap mande
si RC ki kòrèk,

288
00:12:20,620 --> 00:12:23,250
ou ka fè yon bagay jis tankou Enprime RC.

289
00:12:23,250 --> 00:12:24,380

290
00:12:24,380 --> 00:12:28,640
RC se de, ki se
ki sa nou espere, dwa?

291
00:12:28,640 --> 00:12:32,010
>> Se konsa, nou ka ale Next,
yo e yo kontinye a.

292
00:12:32,010 --> 00:12:33,200
Se konsa, nou gen kèk kle a.

293
00:12:33,200 --> 00:12:34,260

294
00:12:34,260 --> 00:12:37,090
Apre sa, nou ka enprime soti kle nou
a asire w ke nan kòrèk.

295
00:12:37,090 --> 00:12:38,380

296
00:12:38,380 --> 00:12:39,500
Enteresan.

297
00:12:39,500 --> 00:12:41,210
Pa byen ki sa nou espere.

298
00:12:41,210 --> 00:12:44,810
Se konsa, yon sèl bagay yo reyalize
ak gdb tou, se

299
00:12:44,810 --> 00:12:49,000
ke li pa jiskaske ou aktyèlman frape
Apre sa, ke liy la ke ou jis te wè

300
00:12:49,000 --> 00:12:50,720
se aktyèlman egzekite.

301
00:12:50,720 --> 00:12:53,870
Se konsa, nan sa a kle ka
pa te asiyen ankò.

302
00:12:53,870 --> 00:12:57,050
Se konsa, kle a se kèk valè fatra
sa ou wè sou anba a la.

303
00:12:57,050 --> 00:13:03,680
Negatif $ 120-- --Sa a yon milya
ak yon bagay bagay enpè dwa?

304
00:13:03,680 --> 00:13:05,340
Li pa kle a ke nou espere.

305
00:13:05,340 --> 00:13:10,720
Men, si nou frape Next, ak lè sa a nou
eseye ak kle Enprime, li nan twa.

306
00:13:10,720 --> 00:13:11,710
>> Tout moun wè sa?

307
00:13:11,710 --> 00:13:13,780
Se konsa, si ou jwenn yon bagay
ke w ap tankou, rete tann.

308
00:13:13,780 --> 00:13:15,540
Sa a se konplètman
sa ki mal, epi mwen pa konnen

309
00:13:15,540 --> 00:13:20,150
ki jan sa a ta rive paske tout mwen vle
fè se bay yon nimewo, yon varyab,

310
00:13:20,150 --> 00:13:22,900
eseye frape Next, eseye enprime
l 'ankò, ak wè si ki travay.

311
00:13:22,900 --> 00:13:27,830
Paske li nan sèlman pral egzekite ak
aktyèlman asiyen yon bagay apre ou

312
00:13:27,830 --> 00:13:29,340
frape Next.

313
00:13:29,340 --> 00:13:30,336
Fè sans a tout moun?

314
00:13:30,336 --> 00:13:30,836
Uh huh?

315
00:13:30,836 --> 00:13:33,220
>> Oratè 2: Lè ou o aza
nimewo ki sa sa vle di?

316

317
00:13:34,790 --> 00:13:35,710
Se jis nan fatra.

318
00:13:35,710 --> 00:13:38,320

òdinatè ap owaza asiyen.

Fre.

321
00:13:40,220 --> 00:13:45,760
Se konsa, kounye a nou ka deplase atravè, ak pou
kounye a nou gen sa a GetString tèks plenn.

322
00:13:45,760 --> 00:13:48,600
Se konsa, kite m 'jis entwodui sa
pral rive lè nou frape Next isit la.

323
00:13:48,600 --> 00:13:51,320
Gdb nou kalite disparèt, dwa?

324
00:13:51,320 --> 00:13:55,720
Sa a se paske GetString
se kounye a egzekite, dwa?

325
00:13:55,720 --> 00:14:01,460
Se konsa, lè nou te wè tèks plenn egal
GetString, paran ouvè ak paran,

326
00:14:01,460 --> 00:14:04,380
epi nou frape Next, ki gen
aktyèlman egzekite kounye a.

327
00:14:04,380 --> 00:14:06,580
Se konsa, li nan ap tann pou
nou nan yon bagay D '.

328
00:14:06,580 --> 00:14:13,560
>> Se konsa, nou ap ale nan D 'manje nou ki
se sa ki li nan li pap resevwa kòm mwen te di nou

329
00:14:13,560 --> 00:14:18,020
ak ki jis di ke li nan
fini egzekite, ki fèmen nan

330
00:14:18,020 --> 00:14:19,980
bracket vle di li nan
sòti soti nan sa bouk.

w ke ou ap tout abitye soti nan Seza tande kòz,

333
00:14:25,420 --> 00:14:27,260
sa a se, sa ki nan liy sa a pral fè.

334
00:14:27,260 --> 00:14:32,030
Li nan pou Int mwen egal 0, N egal
Strlèn, tèks plenn, ak Lè sa a,

335
00:14:32,030 --> 00:14:33,960
Mwen se mwens pase n, mwen, plis, plis.

336
00:14:33,960 --> 00:14:35,210
Ki sa ki se sa a riban pral fè?

337

matche ak, la pou premye yon sèl nou an?

Si li nan yon B, li nan tèks plenn I. Nou
ka jwenn enfòmasyon sou moun nan lokalite nou an.

ke sa a Si aktyèlman ègzekutra.

se ranplase ak aritmetik sa a,

sèlman ègzekutra si Si la
kondisyon ki kòrèk dwa?

jis ale nan ale dirèkteman nan liy kap vini an.

364

OK?

365
00:15:46,540 --> 00:15:48,510

Jis tankou sa.

370
00:15:56,280 --> 00:15:59,120
Se konsa, ke nou kapab jwenn info
sou moun nan lokalite nou an isit la,

371
00:15:59,120 --> 00:16:02,575
epi nou wè ke premye nou an
te lèt chanje, dwa?

372

Li nan kounye a yon E, kòm li ta dwe.

373
00:16:05,150 --> 00:16:07,360
Se konsa, nou ka kontinye sou.

374

375
00:16:08,500 --> 00:16:09,916
Epi chèk sa-a yo ta dwe travay, dwa?

376
00:16:09,916 --> 00:16:12,570
Li nan A. Li ta dwe chanje
twa lèt pou pi devan.

377

378
00:16:14,320 --> 00:16:16,530
Men, si w remake, nou
jwenn yon bagay diferan.

379
00:16:16,530 --> 00:16:17,580

380
00:16:17,580 --> 00:16:22,860

li, epi se konsa liy sa a egzekite,

381
00:16:22,860 --> 00:16:28,620
ki modifye B. nou an
Men, nan ka sa a isit la,

382
00:16:28,620 --> 00:16:32,860
nou gen ke li jis sote li,
l 'al jwenn [a? L siff. ?]

383
00:16:32,860 --> 00:16:34,660
Se konsa, yon bagay k ap pase sou la.

384
00:16:34,660 --> 00:16:37,780
Ki sa ki ki nan di ou se ke,
nou konnen ke li ta dwe trape isit la,

385
00:16:37,780 --> 00:16:39,200
men li la pa.

386
00:16:39,200 --> 00:16:42,210
Èske nenpòt moun kapab wè sa ki nou an
pwoblèm se nan ki liy?

387
00:16:42,210 --> 00:16:45,380

388
00:16:45,380 --> 00:16:46,969
Li se yon bagay trè minit.

389
00:16:46,969 --> 00:16:48,510
Epi ou ta ka tou gade nan kòd ou a.

390
00:16:48,510 --> 00:16:49,980

391
00:16:49,980 --> 00:16:54,940

nan there-- men li la nan [fèbl a].

392
00:16:54,940 --> 00:16:55,480
Wi?

paj si ou li li l 'nan liv la.

Oratè 1: Egzakteman.

395
00:16:59,430 --> 00:17:02,620
Se konsa, debugjeur a pa te kapab di
ou sa, men debugjeur a

396
00:17:02,620 --> 00:17:05,880
te kapab fè ou jwenn desann nan yon liy
ke ou konnen se pa fonksyone.

397
00:17:05,880 --> 00:17:09,319
Epi pafwa, lè espesyalman
pita nan semès la, lè

398
00:17:09,319 --> 00:17:12,910
ou ap fè fas ak yon santèn, yon
san liy kèk nan kòd, epi ou

399
00:17:12,910 --> 00:17:16,190
pa konnen ki kote li nan li pap resevwa,
sa a se yon bon fason yo fè li.

00:17:16,190 --> 00:17:17,900

401
00:17:17,900 --> 00:17:18,989
Se konsa, nou te jwenn ensèk nou an.

402
00:17:18,989 --> 00:17:21,530
Ou ka fikse li nan dosye ou,
ak Lè sa a ou ta ka kouri l 'ankò,

403
00:17:21,530 --> 00:17:23,029
ak tout bagay ta travay pafètman.

404
00:17:23,029 --> 00:17:24,970

405
00:17:24,970 --> 00:17:30,590
Epi bagay la pi gwo se
sa a ka sanble tankou, OK.

406
00:17:30,590 --> 00:17:31,090
Yeah.

407
00:17:31,090 --> 00:17:31,370

Se konsa, ou te konnen sa yo dwe fè.

410
00:17:34,910 --> 00:17:39,021
>> Gdb kapab super itil paske ou
ka enprime soti tout bagay sa yo ke ou

411
00:17:39,021 --> 00:17:39,520
ta pa.

412
00:17:39,520 --> 00:17:41,160
Li nan pi plis itil pase printf.

413
00:17:41,160 --> 00:17:43,440
Konbyen nan ou itilize
tankou printf deklarasyon

414
00:17:43,440 --> 00:17:46,200
konnen ki kote yon ensèk te, dwa?

415
00:17:46,200 --> 00:17:48,450
Se konsa, ak sa a, ou pa fè sa
gen kenbe pral tounen,

416
00:17:48,450 --> 00:17:51,139
ak renmen fè kòmantè nan
Printf, oswa fè kòmantè soti,

417
00:17:51,139 --> 00:17:52,930
ak figi konnen ki sa ki
ou ta dwe enprime.

418
00:17:52,930 --> 00:17:55,670
Sa a aktyèlman jis pèmèt ou
etap nan, enprime soti bagay sa yo

419
00:17:55,670 --> 00:18:00,000
kòm w ap ale atravè tout, se konsa, ou kapab
obsève ki jan yo chanje nan tan reyèl,

420
00:18:00,000 --> 00:18:02,190
kòm pwogram ou an ap kouri.

421
00:18:02,190 --> 00:18:04,390
>> Epi li pran yon ti kras
ti jan nan ap resevwa itilize yo.

422
00:18:04,390 --> 00:18:07,850
Mwen ta trè rekòmande jis kalite
pou yo te yon ti kras fristre ak li

423
00:18:07,850 --> 00:18:08,930
pou kounye a.

424
00:18:08,930 --> 00:18:13,450

semèn pwochèn aprann kouman yo sèvi ak gdb,

425
00:18:13,450 --> 00:18:16,140
ou pral sove tèt ou
tan tèlman pita sou.

426
00:18:16,140 --> 00:18:18,750
Ak literalman. nou di
sa a nan moun chak ane,

427
00:18:18,750 --> 00:18:23,890
ak Mwen sonje lè mwen te pran nan
klas, mwen te tankou, mwen pral vin amann.

No

429
00:18:24,700 --> 00:18:27,030
Pset 6 te vin sou epi mwen te
tankou, mwen pral aprann

430
00:18:27,030 --> 00:18:29,500
kouman yo sèvi ak gdb paske mwen pa fè sa
konnen ki sa k ap pase sou isit la.

431
00:18:29,500 --> 00:18:32,940
>> Se konsa, si ou pran tan an pou
sèvi ak li sou ki pi piti pwogram

00:18:32,940 --> 00:18:35,697
ke w ap ale nan dwe
ap travay sou, tankou k ap travay

433

435
00:18:38,800 --> 00:18:42,850
Oswa si ou vle pratik siplemantè, mwen si ke
Mwen te kapab vini ak pwogram buggy,

436
00:18:42,850 --> 00:18:45,300
pou ou pou w debug si ou ta renmen.

437
00:18:45,300 --> 00:18:49,300
>> Men, si ou jis pran kèk tan yo ka resevwa
itilize li, jis jwe otou ak li,

438
00:18:49,300 --> 00:18:50,550
li pral vrèman sèvi ou byen.

439
00:18:50,550 --> 00:18:52,591
Epitou, se vrèman youn nan
bagay sa yo ke ou jis

440

gen eseye, epi pou yo jwenn men ou sal
ak, anvan ou reyèlman konprann li.

441
00:18:57,340 --> 00:19:02,090
Mwen vrèman sèlman konprann li yon fwa
Mwen te oblije dbug bagay ak li,

442
00:19:02,090 --> 00:19:08,170
ak li a anpil joli gen yon lide sou
ki jan yo debug pi bonè olye ke pi ta.

443
00:19:08,170 --> 00:19:08,850
OK.

Fre.

445
00:19:09,625 --> 00:19:12,960
Mwen konnen sa a, se kalite tankou
yon kou aksidan nan gdb,

446
00:19:12,960 --> 00:19:16,400
epi mwen pral definitivman travay sou ap resevwa
sa yo gade pi gwo tan kap vini an.

Mwen pa reyèlman jwenn nan
liv telefòn ankò,

Oratè 5: Ou konnen ki lè
ou gade nan ki mwatye

470

li ta nan, Baze sou sa,
ak debarase m de lòt mwatye a.

Se konsa, binè Search, li nan kalite a--
--we renmen rele li divize ak konkeri.

473
00:20:06,290 --> 00:20:09,170
Se konsa, sa ou pral fè se
ou pral gade nan mitan an,

474
00:20:09,170 --> 00:20:11,990
epi ou pral wè si li matche
ki sa w ap chèche pou.

475

477
00:20:16,450 --> 00:20:19,325
Se konsa, sa a ta kapab si w ap chèche
nan yon bagay ki nan alphabetized,

478
00:20:19,325 --> 00:20:20,720

Wi.

Se konsa, nenpòt moun ki sonje sa a
graf oswa sa ki sa a se?

488
00:20:37,455 --> 00:20:39,520
Li nan konpleksite asenptotik.

489
00:20:39,520 --> 00:20:42,830

dekri konbyen tan li

ou ogmante kantite a nan bagay sa yo

pi bon, toujou ap grandi Super vit.

Lè sa a, nou te Login, ki se
ki sa nou konsidere binè rechèch la.

vin anpil ak pi gwo,

496

tan an li pran ou nan rezoud li
pa reyèlman ogmante ki anpil.

497
00:21:06,600 --> 00:21:09,010
Se tankou konparab
isit la nan konmansman an.

498
00:21:09,010 --> 00:21:10,060
Ou se tankou, OK.

499
00:21:10,060 --> 00:21:13,000
Nenpòt bagay isit la pa reyèlman
pwoblèm ki youn nou itilize,

500
00:21:13,000 --> 00:21:16,220
men ou jwenn soti nan yon milyon dola, yon milya dola.

501
00:21:16,220 --> 00:21:20,010
W ap ap eseye jwenn some-- --you're
ap eseye jwenn yon zegwi nan yon gwo pile zèb.

502
00:21:20,010 --> 00:21:21,550
>> Mwen panse ke ou vle pwoblèm sa a.

503
00:21:21,550 --> 00:21:25,850
Ou vle konpleksite sa a, pa

ap eseye gade pou zegwi ou yo.

506

Ak elèv kòm travay di ou
nèg yo se, ou konnen travay pi entelijan,

510

pa pi rèd bagay kalite, ki jan ou
ka fè moute algoritm sa yo.

a jis yon egzanp rapid.

513
00:21:47,910 --> 00:21:51,090
Mwen panse ke ou nèg ta dwe gen
yon men sou rechèch binè,

514
00:21:51,090 --> 00:21:54,352
men nan ka nenpòt moun ki se yon ti kras
mou, vle ranfòse li,

515
00:21:54,352 --> 00:21:56,310
nou ap ale nan jis ale
atravè yon egzanp isit la.

516
00:21:56,310 --> 00:21:59,490
Se konsa, nou ap chèche pou si
etalaj la gen sèt.

517
00:21:59,490 --> 00:22:00,540

518
00:22:00,540 --> 00:22:06,010
>> Se konsa, premye bagay nou fè se
gade nan mitan an, dwa?

Epi tou ou ap ale nan dwe kodaj
Search binè nan jis yon dezyèm fwa.

520
00:22:09,340 --> 00:22:11,310
Se konsa, li nan pral fè plezi.

521
00:22:11,310 --> 00:22:13,710
Se konsa, nou gade nan la
mitan ranje ti kras 3.

522
00:22:13,710 --> 00:22:15,501
3 egal 7?

523
00:22:15,501 --> 00:22:16,000
Pa fè sa.

524
00:22:16,000 --> 00:22:18,670

525
00:22:18,670 --> 00:22:19,550
Li nan sis.

526
00:22:19,550 --> 00:22:21,480
Se konsa, se li mwens pase
oswa pi gran pase sèt?

527
00:22:21,480 --> 00:22:23,080

528
00:22:23,080 --> 00:22:23,960
Mwens pase.

Wi.

530
00:22:24,570 --> 00:22:25,170
Mesye travay bèl.

00:22:25,170 --> 00:22:25,569

532
00:22:25,569 --> 00:22:27,360
Mwen santi mwen mwen renmen mwen ta dwe
gen sirèt paske mwen

533
00:22:27,360 --> 00:22:29,460
vle voye jete li soti nan yad yo.

534
00:22:29,460 --> 00:22:30,270
Li nan sa m ap pral fè semèn pwochèn.

00:22:35,670 --> 00:22:39,325
nou konnen ke tout bagay
sou sa bò men gòch

a pwal mwens pase sa
nou ap aktyèlman kap chèche.

541
00:22:41,700 --> 00:22:43,491
Se konsa, gen nan pa gen bezwen
peye atansyon sou li.

542
00:22:43,491 --> 00:22:45,120
Jis bliye sou li.

543
00:22:45,120 --> 00:22:48,720
Se konsa, kounye a nou gade nan bò men dwat nou an,
epi nou gade nan mitan an lòt bò a,

544
00:22:48,720 --> 00:22:50,510
e kounye a, li nan nèf.

545
00:22:50,510 --> 00:22:55,510
Se konsa, 9 is-- --Everyone?

546

Greater pase sa nou ap
chèche pou yo, dwa?

547
00:22:57,470 --> 00:22:59,860
Se konsa, nou ap ale nan voye jete
lwen tout bagay a dwat la.

549
00:23:00,970 --> 00:23:01,940

>> Men, si w remake, nou
te gen sèt entrain la.

557
00:23:15,740 --> 00:23:24,320
Li sèlman pran nou tankou twa fwa,
men si w ap fè tankou yon milya dola,

558
00:23:24,320 --> 00:23:28,190
ou nèg konnen ki jan anpil etap li ta
pran si nou te gen kat milya dola bagay sa yo?

kat milya dola eleman.

Apre sa, tout mwen vle nan men ou
mesye kounye a se jis

577

Se konsa, nenpòt moun ki gen nenpòt ki
kesyon sou rechèch binè?

808
00:34:05,370 --> 00:34:06,196
Wi.

>> Enstriktè: No

811
00:34:10,750 --> 00:34:18,150
Paske nou voye l 'jete nan mitan an kòm
yon int, li pral jis tronke li.

812
00:34:18,150 --> 00:34:21,600
Se konsa, li ap rete yon nonb antye relatif epi li pral
evantyèlman sòt nan tout bagay.

813

Se konsa, ou pa gen enkyete sou sa.

Tout moun sa ki bon?

815
00:34:24,580 --> 00:34:25,659

816
00:34:25,659 --> 00:34:26,850

832
00:35:00,789 --> 00:35:03,830
Enstriktè: Se konsa, mitan an ke yo te nan
premye eleman ki nou vini nan, dwa?

833
00:35:03,830 --> 00:35:08,167
Se konsa, swa yon etalaj de youn oswa
tou sa nou ap chèche pou jis

834

Ka pi mal nou se boutèy demi lit n.

841
00:35:21,270 --> 00:35:25,360
Epi sa te fè avèk tout la
pouvwa nan de bagay ke mwen te pale osijè de.

842
00:35:25,360 --> 00:35:30,930
>> Se konsa, nan ka ki pi mal li ta vle di
ke nou te koupe etalaj la desann

843
00:35:30,930 --> 00:35:33,270

Nimewo ak nimewo a M 'ap chache

855

oswa li pran ou etap siplemantè
pou li ale nan ki eleman presegondè,

864

w ap ajoute plis travay nan li.

plis sans nan de semèn,

ou nèg kounye a.

rès la nan kalite nou an.

se yon sou vrèman fre komik

trè rekòmande ou pral fè yon gade nan.

878

konnen ke pi gwo nimewo ou

927
00:38:54,980 --> 00:38:55,920
Sis ak de, switch.

928
00:38:55,920 --> 00:38:58,700
Epi, koulye a nou gen yon bagay kèk yo nan lòd.

929
00:38:58,700 --> 00:39:02,240
Se konsa, pou chak pas ke nou
fè nan lis tout antye nou an,

930
00:39:02,240 --> 00:39:06,320
nou konnen ke tankou sa nimewo anpil
nan fen a pral yo te Ranje.

931
00:39:06,320 --> 00:39:07,690

932
00:39:07,690 --> 00:39:09,610
Se konsa, nou fè yon pas twazyèm,
ki se youn swap.

933
00:39:09,610 --> 00:39:10,860

934
00:39:10,860 --> 00:39:15,910
Lè sa a, sou katriyèm nou an
pase, nou gen zewo fant.

935
00:39:15,910 --> 00:39:18,570
Se konsa, nou konnen ke nou an
te etalaj te Ranje.

936

>> E ke se gwo nan
bagay ak sòt jarèt.

937
00:39:20,900 --> 00:39:23,720
Nou konnen ke lè nou
gen zewo echanj, ki

938
00:39:23,720 --> 00:39:26,497
vle di ke tout bagay
ki nan lòd konplè.

939
00:39:26,497 --> 00:39:27,580

940
00:39:27,580 --> 00:39:28,740

941
00:39:28,740 --> 00:39:36,480
Se konsa, nou yo tou ale nan Kòd jarèt
sòt ki tou se pa sa ki move.

942
00:39:36,480 --> 00:39:38,120
Okenn nan sa yo, se sa ki move.

943
00:39:38,120 --> 00:39:40,210
Mwen konnen yo ka sanble yon ti kras pè.

944
00:39:40,210 --> 00:39:42,124
Mwen konnen lè m 'te pran
klas la, menm lè mwen

945
00:39:42,124 --> 00:39:44,290
t ap anseye klas la pou
premye fwa nan ane pase a,

946
00:39:44,290 --> 00:39:46,165
Mwen te tankou, ki jan mwen fè sa?

947
00:39:46,165 --> 00:39:48,540
Li fè sans nan teyori, men
ki jan nou aktyèlman fè sa a?

948
00:39:48,540 --> 00:39:51,420
Ki se poukisa mwen vle tou yo mache
nan kòd avèk ou guys isit la.

949
00:39:51,420 --> 00:39:54,915
Se konsa, mwen gen yon pseudocode
pou ou nèg tan sa a.

00:39:54,915 --> 00:39:55,950

951
00:39:55,950 --> 00:39:58,970
Se konsa, jis kenbe sa a nan tèt ou kòm
nou ap sou yo tranzisyon sou.

952
00:39:58,970 --> 00:40:04,210
Se konsa, nou gen kèk vann san preskripsyon ki
kenbe yon dosye sou echanj nou an,

953
00:40:04,210 --> 00:40:08,370
paske nou bezwen asire w
ke nou ap tcheke sa.

954
00:40:08,370 --> 00:40:11,830
Apre sa, nou repekte etalaj nan tout
kòm nou jis te fè ak egzanp sa a.

955
00:40:11,830 --> 00:40:12,900

956
00:40:12,900 --> 00:40:17,325
Si eleman nan anvan se pi gwo pase
eleman nan apre kote nou ap nan,

957
00:40:17,325 --> 00:40:20,760
nou boukante yo epi nou kantite nou an
vann san preskripsyon paske le pli vit ke nou boukante,

958
00:40:20,760 --> 00:40:23,850
nou vle kite kontwa nou konnen sa.

959
00:40:23,850 --> 00:40:26,247
Nenpòt kesyon genyen?

960
00:40:26,247 --> 00:40:27,580
Yon bagay sanble komik sou isit la.

961
00:40:27,580 --> 00:40:29,225

962
00:40:29,225 --> 00:40:32,350
ELÈV: ou mete kontwa an nan zewo
chak fwa ou ale nan riban an?

963
00:40:32,350 --> 00:40:34,339
ou pa kenbe prale
tounen nan zewo chak fwa?

964
00:40:34,339 --> 00:40:35,505
Enstriktè: Pa nesesèman.

965
00:40:35,505 --> 00:40:39,710
Se konsa, sa k ap pase se nou ale nan isit la.

966
00:40:39,710 --> 00:40:43,830
Se konsa, fè ti tan, sonje, sa a
ap egzekite yon fwa san yo pa febli.

967
00:40:43,830 --> 00:40:46,480
Se konsa, li pral mete nan
vann san preskripsyon egal a zewo,

968
00:40:46,480 --> 00:40:48,070
Lè sa a, li nan ale nan repekte nan.

969
00:40:48,070 --> 00:40:50,590
Kòm li iterates a,
li pral mete ajou vann san preskripsyon.

970
00:40:50,590 --> 00:40:51,870

971
00:40:51,870 --> 00:40:56,900
Kòm li dènye nouvèl vann san preskripsyon, lè li fè,
lè li nan te rive nan fen a nan etalaj la,

972
00:40:56,900 --> 00:41:00,830
si lis nou an pa te Ranje,
vann san preskripsyon pral yo te mete ajou.

973
00:41:00,830 --> 00:41:01,840

974
00:41:01,840 --> 00:41:07,150
>> Se konsa, Lè sa a, li tcheke kondisyon an epi li
di, OK, se vann san preskripsyon pi gran pase zewo.

975
00:41:07,150 --> 00:41:09,290
Si li se, fè l 'ankò.

976
00:41:09,290 --> 00:41:14,340
Ou vle Reyajiste pou ke lè ou
ale nan, vann san preskripsyon ki egal a zewo.

977
00:41:14,340 --> 00:41:18,240
Si ou ale nan yon Ranje
etalaj, chanjman pa gen anyen,

978
00:41:18,240 --> 00:41:21,355
sa a echwe, epi ou
retounen lis la Ranje.

979
00:41:21,355 --> 00:41:23,104

980
00:41:23,104 --> 00:41:24,020
Èske sa fè sans?

981
00:41:24,020 --> 00:41:24,940

982
00:41:24,940 --> 00:41:26,356
ELÈV: Li ta ka nan yon ti jan ti kras.

983
00:41:26,356 --> 00:41:27,147
Enstriktè: OK.

984
00:41:27,147 --> 00:41:28,980
Si gen nan nenpòt lòt
kesyon ki vini leve.

985
00:41:28,980 --> 00:41:30,180

986
00:41:30,180 --> 00:41:30,680
Wi.

987
00:41:30,680 --> 00:41:33,760
>> ELÈV: Ki sa ki ta fonksyon an
dwe pou échanjé eleman yo?

988
00:41:33,760 --> 00:41:36,900
>> Enstriktè: Se konsa, nou ka aktyèlman ekri
ke si nou ap ale nan kounye a.

989
00:41:36,900 --> 00:41:37,801

990
00:41:37,801 --> 00:41:38,300
Fre.

991
00:41:38,300 --> 00:41:42,155
Se konsa, sou ki nòt, Alison ki pral
chanje tounen nan aparèy la.

992
00:41:42,155 --> 00:41:43,080
Li nan ale nan dwe plezi.

993
00:41:43,080 --> 00:41:45,170

994
00:41:45,170 --> 00:41:47,390
Epi nou gen bèl nou an
ti wonn sòt bagay isit la.

995
00:41:47,390 --> 00:41:50,800
Se konsa, mwen deja te fè monte bisiklèt
nan etalaj la.

996
00:41:50,800 --> 00:41:53,030
Nou gen echanj nou an ki
yo egal a zewo.

997
00:41:53,030 --> 00:41:54,480

998
00:41:54,480 --> 00:41:58,440
Se konsa, nou vle swap adjasan
eleman si yo ap parèt nan lòd.

999
00:41:58,440 --> 00:42:03,020
Se konsa, premye bagay la nou bezwen
se repekte nan etalaj nou an.

1000
00:42:03,020 --> 00:42:04,500

1001
00:42:04,500 --> 00:42:08,260
>> Se konsa, kouman ou panse nou ta ka
repekte nan etalaj nou an?

1002
00:42:08,260 --> 00:42:09,720

1003
00:42:09,720 --> 00:42:13,990
Nou gen pou ak mwen egal 0.

1004
00:42:13,990 --> 00:42:16,950

1005
00:42:16,950 --> 00:42:22,454
Nou vle m li dwe mwens
pase n mwens 1 mwens k.

1006
00:42:22,454 --> 00:42:23,870
Apre sa, mwen pral eksplike ke nan yon dezyèm fwa.

1007
00:42:23,870 --> 00:42:26,280

1008
00:42:26,280 --> 00:42:32,830
Se konsa, sa a se yon optimize isit la ki kote,
sonje ki jan mwen te di apre chak pas

1009
00:42:32,830 --> 00:42:36,655
a nou nan etalaj
konnen tou sa la on--

1010
00:42:36,655 --> 00:42:43,590

1011
00:42:43,590 --> 00:42:46,295
>> Se konsa, apre yon sèl pas nou
konnen ke sa a se Klase.

1012
00:42:46,295 --> 00:42:47,370

1013
00:42:47,370 --> 00:42:50,060
Apre de pass nou konnen
ke tout sa a se Klase.

1014
00:42:50,060 --> 00:42:52,750
Apre twa pass nou
konnen ke nan Ranje.

1015
00:42:52,750 --> 00:42:55,620
Se konsa, wout la mwen iteration
nan etalaj la isit la,

1016
00:42:55,620 --> 00:43:01,090
se li nan fè asire w ke ou sèlman ale
nan sa ki nou konnen se klase.

1017
00:43:01,090 --> 00:43:01,644
OK?

1018
00:43:01,644 --> 00:43:02,810
Se jis yon optimize.

1019
00:43:02,810 --> 00:43:04,430

1020
00:43:04,430 --> 00:43:08,210
Ou te kapab ekri li naivman jis
iteration nan tout bagay,

1021
00:43:08,210 --> 00:43:09,970
li ta jis pran plis tan.

1022
00:43:09,970 --> 00:43:12,470
Avèk sa a riban kat li a
jis yon optimize bèl

1023
00:43:12,470 --> 00:43:18,460
paske nou konnen ke apre chak plen
iterasyon nan etalaj la isit la,

1024
00:43:18,460 --> 00:43:24,050
tankou chak bouk plen isit la, nou konnen
ki yon sèl plis nan eleman sa yo

1025
00:43:24,050 --> 00:43:25,760
pral dwe klase nan fen an.

1026
00:43:25,760 --> 00:43:28,294
>> Se konsa, nou pa gen enkyete sou sa yo.

1027
00:43:28,294 --> 00:43:29,710
Èske sa fè sans a tout moun?

1028
00:43:29,710 --> 00:43:30,950
Sa fre ti kras Trick?

1029
00:43:30,950 --> 00:43:32,060

1030
00:43:32,060 --> 00:43:37,270
Se konsa, nan ka sa a, si
nou ap iteration nan,

1031
00:43:37,270 --> 00:43:50,590
nou konnen ke nou vle tcheke si
etalaj n ak n plis 1 yo nan lòd.

1032
00:43:50,590 --> 00:43:52,640

1033
00:43:52,640 --> 00:43:53,559
OK.

1034
00:43:53,559 --> 00:43:54,600
Se konsa, isit la nan pseudocode la.

1035
00:43:54,600 --> 00:43:57,540
Nou vle tcheke si etalaj n
ak n plis 1 yo nan lòd.

1036
00:43:57,540 --> 00:43:59,520
Se konsa, sa nou ka gen la?

1037
00:43:59,520 --> 00:44:01,090

1038
00:44:01,090 --> 00:44:03,120
Li nan ale nan gen kèk kondisyonèl.

1039
00:44:03,120 --> 00:44:04,220
Li pral yon si.

1040
00:44:04,220 --> 00:44:07,066
>> ELÈV: Si etalaj n se
mwens pase etalaj n plis 1.

1041
00:44:07,066 --> 00:44:07,816
Enstriktè: Milimèt-HM.

1042
00:44:07,816 --> 00:44:09,000

1043
00:44:09,000 --> 00:44:10,699
Oke, mwens pase oswa pi gran pase.

1044
00:44:10,699 --> 00:44:11,615
ELÈV: Pi gran pase.

1045
00:44:11,615 --> 00:44:15,850

1046
00:44:15,850 --> 00:44:17,620
Lè sa a, nou vle swap yo.

1047
00:44:17,620 --> 00:44:18,570
Egzakteman.

1048
00:44:18,570 --> 00:44:23,570
Se konsa, kounye a nou jwenn nan sa ki nan la
mekanis pou échanjé yo?

1049
00:44:23,570 --> 00:44:24,840

1050
00:44:24,840 --> 00:44:28,137
Se konsa, nou te ale nan yon ti tan sa a,
yon kalite fonksyon swap semèn pase a.

1051
00:44:28,137 --> 00:44:29,595
nenpòt moun ki sonje ki jan li te travay?

1052
00:44:29,595 --> 00:44:32,300

1053
00:44:32,300 --> 00:44:34,950
Se konsa, nou pa ka jis mute yo, dwa?

1054
00:44:34,950 --> 00:44:36,640
Paske yon sèl nan yo ap jwenn pèdi.

1055
00:44:36,640 --> 00:44:41,696
Si nou di A se egal a B ak Lè sa a B
ki egal a A, tout yon toudenkou tou de peyi yo

1056
00:44:41,696 --> 00:44:43,150
yo se jis egal a B.

1057
00:44:43,150 --> 00:44:45,720
>> Se konsa, sa nou dwe fè se nou
gen yon varyab tanporè sa a, se

1058
00:44:45,720 --> 00:44:49,055
ale nan kenbe youn nan nou pandan y ap
nou ap nan pwosesis la nan échanjé.

1059
00:44:49,055 --> 00:44:50,200

1060
00:44:50,200 --> 00:44:56,464
Se konsa, sa nou genyen se nou pral gen kèk Int
temp ki egal to-- ou ka bay li

1061
00:44:56,464 --> 00:44:59,130
kèlkeswa sa ki yon sèl ou vle, jis
asire w ke ou kenbe tras nan l--

1062
00:44:59,130 --> 00:45:01,840
se konsa nan ka sa a, mwen pral
asiyen li nan etalaj n plis 1.

1063
00:45:01,840 --> 00:45:03,360

1064
00:45:03,360 --> 00:45:07,674
Se konsa, ki k ap pase yo kenbe tou sa
valè nan ki dezyèm blòk

1065
00:45:07,674 --> 00:45:08,590
ke nou ap chèche a.

1066
00:45:08,590 --> 00:45:09,700

1067
00:45:09,700 --> 00:45:13,240
>> Lè sa a, nou ka fè se nou ka ale
pi devan epi etalaj REASSIGN n plis 1,

1068
00:45:13,240 --> 00:45:14,990
paske nou konnen nou
gen ki valè ki estoke.

1069
00:45:14,990 --> 00:45:16,645

1070
00:45:16,645 --> 00:45:19,270
Sa a se tou youn nan gwo a
things-- Mwen pa konnen si nenpòt nan ou

1071
00:45:19,270 --> 00:45:23,780
te gen pwoblèm kote si ou chanje de
liy nan kòd toudenkou bagay te travay.

1072
00:45:23,780 --> 00:45:25,880
Lòd trè enpòtan nan CS.

1073
00:45:25,880 --> 00:45:29,450
Se konsa, asire w ke ou dyagram
bagay sa yo soti si sa posib

1074
00:45:29,450 --> 00:45:31,230
tankou sa ki la aktyèlman pase.

1075
00:45:31,230 --> 00:45:34,256
Se konsa, kounye a nou ap ale nan
mute etalaj n plis 1,

1076
00:45:34,256 --> 00:45:36,005
paske nou konnen nou
gen ki valè ki estoke.

1077
00:45:36,005 --> 00:45:37,090

1078
00:45:37,090 --> 00:45:41,560
>> Apre sa, nou ka bay ke yo etalaj
n oswa nan ka sa a etalaj mwen.

1079
00:45:41,560 --> 00:45:50,540

1080
00:45:50,540 --> 00:45:51,465
Twòp varyab.

1081
00:45:51,465 --> 00:45:54,230

1082
00:45:54,230 --> 00:45:55,470
OK.

1083
00:45:55,470 --> 00:46:01,500
Se konsa, kounye a nou te plase etalaj mwen
plis 1 egal sa ki nan nan etalaj mwen.

1084
00:46:01,500 --> 00:46:08,240
Epi, koulye a nou ka ale retounen lakay yo epi
asiyen etalaj mwen ki sa?

1085
00:46:08,240 --> 00:46:10,680

1086
00:46:10,680 --> 00:46:11,180
Nenpòt moun ki?

1087
00:46:11,180 --> 00:46:13,490

1088
00:46:13,490 --> 00:46:14,010

1092
00:46:16,930 --> 00:46:18,640
Epi yon sèl bagay dènye.

1093
00:46:18,640 --> 00:46:21,840
Si nou te échanges li kounye a,
ki sa nou bezwen fè?

1094
00:46:21,840 --> 00:46:23,740
Ki sa ki nan bagay la yon sèl
ki nan ale nan di nou

1095
00:46:23,740 --> 00:46:27,542
si nou tout tan tout tan mete fen nan pwogram sa a?

1096
00:46:27,542 --> 00:46:29,250
Ki sa ki di nou ke nou
gen yon lis Ranje?

1097
00:46:29,250 --> 00:46:31,560

1098
00:46:31,560 --> 00:46:33,750
Si nou pa fè nenpòt echanj, dwa?

1099
00:46:33,750 --> 00:46:36,900
Si echanj ki egal a
zewo nan fen sa a.

1100
00:46:36,900 --> 00:46:42,975
Se konsa, chak fwa ou fè yon swap, menm jan nou
jis te fè isit la, nou vle mete ajou echanj.

1101
00:46:42,975 --> 00:46:45,002

1102
00:46:45,002 --> 00:46:47,210
Apre sa, mwen konnen te gen yon
kesyon pi bonè sou ou ka

1103
00:46:47,210 --> 00:46:49,689
itilize zewo oswa yon sèl olye pou
a vre oubyen fo.

1104
00:46:49,689 --> 00:46:50,980
Epi sa a, ki sa sa a fè isit la.

1105
00:46:50,980 --> 00:46:52,750
Se konsa, sa a di si se pa echanj.

1106
00:46:52,750 --> 00:47:01,310
Se konsa, si echanj se zewo, ki is-- Mwen toujou
jwenn verite m 'ak fo m' melanje moute.

1107
00:47:01,310 --> 00:47:03,960
Nou vle nou evalye
vre ak li pa.

1108
00:47:03,960 --> 00:47:07,680

1109
00:47:07,680 --> 00:47:09,630
Se konsa, si li nan zewo, Lè sa a, li nan fo.

1110
00:47:09,630 --> 00:47:12,560
Si ou anile li ak yon
[? Bang?] li vin vre.

1111
00:47:12,560 --> 00:47:13,975
Se konsa, Lè sa a, liy sa a ègzekutra.

1112
00:47:13,975 --> 00:47:15,060

1113
00:47:15,060 --> 00:47:17,370
>> Verite ak fo ak
zewo ak moun yo jwenn fou.

00:47:17,370 --> 00:47:20,690
Jis si ou tou dousman mache
atravè li li pral fè sans.

1115
00:47:20,690 --> 00:47:23,320
Men, se sa ki sa a ti kras
ti jan nan Kòd isit la fè.

1116
00:47:23,320 --> 00:47:26,490
Se konsa, sa chèk yo wè
nou fè nenpòt ki echanj.

1117
00:47:26,490 --> 00:47:30,054
Se konsa, si li la anyen san konte
zewo, li pral yo dwe fo

1118
00:47:30,054 --> 00:47:31,970
ak bagay la antye se
ale nan egzekite ankò.

jis tankou fini pwogram nan

ELÈV: Paske deja nou
itilize ekri 1 sou ekri zewo

1130
00:47:52,110 --> 00:47:54,170
prezante ke si
ki pral travay oswa ou pa.

1131
00:47:54,170 --> 00:47:54,878
>> Enstriktè: Yeah.

1132
00:47:54,878 --> 00:47:56,410
Se konsa, ou ka retounen zewo oswa 1.

1133
00:47:56,410 --> 00:47:58,950
Nan ka sa a, paske nou pa ap aktyèlman
fè anyen ak fonksyon an,

1134
00:47:58,950 --> 00:48:00,150
nou jis vle li nan kraze.

1135
00:48:00,150 --> 00:48:02,680
Nou pa reyèlman sousye de li.

1136
00:48:02,680 --> 00:48:06,960
Fren se bon tou si
li nan itilize pou kraze soti

1137
00:48:06,960 --> 00:48:10,710
nan kat pasan oswa kondisyon ki
ou pa vle kenbe egzekite.

1138
00:48:10,710 --> 00:48:12,110
Li jis pran ou soti nan yo.

1139
00:48:12,110 --> 00:48:13,587

1140
00:48:13,587 --> 00:48:14,795
Li se yon ti jan nan yon bagay nuans.

1141
00:48:14,795 --> 00:48:16,737

1142
00:48:16,737 --> 00:48:18,445
Mwen santi mwen tankou gen nan
yon anpil nan leve men,

1143
00:48:18,445 --> 00:48:19,740
tankou ou pral aprann sou sa a byento.

1144
00:48:19,740 --> 00:48:20,955
>> Men, ou pral aprann sou sa a byento.

1145
00:48:20,955 --> 00:48:21,500
Mwen te pwomèt.

1146
00:48:21,500 --> 00:48:22,670

1147
00:48:22,670 --> 00:48:23,170
OK.

1148
00:48:23,170 --> 00:48:24,840
Se konsa, tout moun jwenn sòt jarèt?

1149
00:48:24,840 --> 00:48:25,550
Pa twò move.

1150
00:48:25,550 --> 00:48:31,910
Repekte nan, bagay sa yo swap l sèvi avèk yon
varyab temp, epi nou ap tout mete a?

1151
00:48:31,910 --> 00:48:32,960
Fre.

1152
00:48:32,960 --> 00:48:34,080
Awesome.

1153
00:48:34,080 --> 00:48:34,807
OK.

1154
00:48:34,807 --> 00:48:35,765
Retounen nan PowerPoint la.

1155
00:48:35,765 --> 00:48:38,140

1156
00:48:38,140 --> 00:48:40,130
Nenpòt kesyon an jeneral
sou sa yo byen lwen tèlman?

1157
00:48:40,130 --> 00:48:41,200

1158
00:48:41,200 --> 00:48:41,700
Fre.

1159
00:48:41,700 --> 00:48:43,110

1160
00:48:43,110 --> 00:48:43,695
Milimèt-HM.

1161
00:48:43,695 --> 00:48:45,279
>> ELÈV: [fèbl] Int prensipal anjeneral.

1162
00:48:45,279 --> 00:48:46,695
ou gen gen ke pou sa a?

1163
00:48:46,695 --> 00:48:48,400

1164
00:48:48,400 --> 00:48:53,550
>> Enstriktè: Se konsa, nou te jis kap
jis nan algorithm nan klasman aktyèl.

1165
00:48:53,550 --> 00:48:54,559

1166
00:48:54,559 --> 00:48:56,350
Si ou te gen li nan
tankou yon pwogram pi gwo,

1167
00:48:56,350 --> 00:48:57,891
ou ta gen yon yon kote prensipal Int.

1168
00:48:57,891 --> 00:49:00,070

1169
00:49:00,070 --> 00:49:02,880
Tou depan de ki kote ou
itilize sa a algorithm,

1170
00:49:02,880 --> 00:49:05,860
li ta detèmine sa ki nan
ke yo te tounen pa li.

1171
00:49:05,860 --> 00:49:09,960
Men, pou ka nou an, nou ap estrikteman
gade nan ki jan fè sa sa a aktyèlman

1172
00:49:09,960 --> 00:49:11,300
repekte nan yon etalaj.

1173
00:49:11,300 --> 00:49:12,570
Se konsa, nou pa enkyete sou li.

1174
00:49:12,570 --> 00:49:14,150

1175
00:49:14,150 --> 00:49:19,830
>> Se konsa, nou te pale sou pi bon ka ak
pi move senaryo ka pou rechèch binè.

1176
00:49:19,830 --> 00:49:22,470
Se konsa, li la tou enpòtan fè
ke pou chak nan kalite nou an.

1177
00:49:22,470 --> 00:49:24,200

1178
00:49:24,200 --> 00:49:27,560
Se konsa, sa ou panse se pi move a
ka ègzekutabl nan sòt jarèt?

1179
00:49:27,560 --> 00:49:29,560

1180
00:49:29,560 --> 00:49:30,700
Ou nèg sonje?

1181
00:49:30,700 --> 00:49:31,784
>> ELÈV: N mwens 1.

1182
00:49:31,784 --> 00:49:32,700
Enstriktè: N mwens 1.

1183
00:49:32,700 --> 00:49:35,070
Se konsa, ki vle di gen
n mwens 1 konparezon.

1184
00:49:35,070 --> 00:49:40,060
Se konsa, yon sèl bagay yo reyalize se
ke sou iterasyon an premye,

1185
00:49:40,060 --> 00:49:43,360
nou ale nan, nou konpare
sa yo two-- pou ki nan 1.

1186
00:49:43,360 --> 00:49:46,685
Sa yo de, twa, kat.

1187
00:49:46,685 --> 00:49:48,070

1188
00:49:48,070 --> 00:49:55,050
Se konsa, apre yon sèl iterasyon nou
deja gen kat konparezon.

1189
00:49:55,050 --> 00:49:58,230
Lè m 'ap pale de ègzekutabl ak n.

1190
00:49:58,230 --> 00:50:04,680
N reprezante kantite konparezon
kòm yon fonksyon nan konbyen eleman

1191
00:50:04,680 --> 00:50:05,570
nou genyen.

1192
00:50:05,570 --> 00:50:06,430
OK?

1193
00:50:06,430 --> 00:50:08,860
>> Se konsa, nou ale nan, nou gen kat.

1194
00:50:08,860 --> 00:50:11,780
Tan nan pwochen ou konnen nou pa fè sa
dwe pran swen nan sa a.

1195
00:50:11,780 --> 00:50:15,140
Nou konpare de sa yo,
sa yo de, de sa yo,

1196
00:50:15,140 --> 00:50:20,050
epi si nou pa t 'gen ki optimize
ak riban an kat ke mwen te ekri,

1197
00:50:20,050 --> 00:50:22,750
ou ta dwe konpare nan isit la aniwe.

1198
00:50:22,750 --> 00:50:26,170
Se konsa, ou ta gen yo
kouri nan etalaj la

1199
00:50:26,170 --> 00:50:34,380
epi fè konparezon n n
fwa, paske chak nou tan

1200
00:50:34,380 --> 00:50:36,670
kouri atravè li nou sòt yon sèl bagay.

1201
00:50:36,670 --> 00:50:38,300

1202
00:50:38,300 --> 00:50:41,475
>> Epi chak fwa nou kouri nan
etalaj la, nou fè konparezon n.

1203
00:50:41,475 --> 00:50:42,920

1204
00:50:42,920 --> 00:50:46,330
Se konsa, ègzekutabl nou an pou sa a se
aktyèlman n okib, ki

1205
00:50:46,330 --> 00:50:48,400
se pi mal nan nou an
journal fen paske sa

1206
00:50:48,400 --> 00:50:51,965
vle di si nou te gen kat
milya dola eleman, li nan

1207
00:50:51,965 --> 00:50:55,260
pral pran nou kat milya dola
okib olye pou yo 32.

1208
00:50:55,260 --> 00:51:01,240
Se konsa, pa ègzekutabl a pi bon,
men pou kèk bagay sa yo,

1209
00:51:01,240 --> 00:51:04,610
ou konnen, si w ap nan
yon seri sèten nan eleman

1210
00:51:04,610 --> 00:51:06,540
sòt jarèt ka dwe amann yo sèvi ak.

1211
00:51:06,540 --> 00:51:07,530
>> OK.

1212
00:51:07,530 --> 00:51:12,290
Se konsa, kounye ki sa ki ègzekutabl a ka pi bon?

1213
00:51:12,290 --> 00:51:14,357

1214
00:51:14,357 --> 00:51:14,940
ELÈV: Zewo?

1215
00:51:14,940 --> 00:51:16,420
Oswa 1?

1216
00:51:16,420 --> 00:51:18,140
>> Enstriktè: Se konsa, 1 ta
fè yon sèl konparezon.

1217
00:51:18,140 --> 00:51:19,114
Dwa.

1218
00:51:19,114 --> 00:51:20,002
>> ELÈV: N mwens 1?

1219
00:51:20,002 --> 00:51:21,380

1220
00:51:21,380 --> 00:51:22,320
>> Enstriktè: Se konsa, yeah.

1221
00:51:22,320 --> 00:51:22,990
Se konsa, n mwens 1.

1222
00:51:22,990 --> 00:51:26,510
Chak fwa ou gen yon konsèp tankou n
mwens 1, nou gen tandans jis depoze li

1223
00:51:26,510 --> 00:51:31,680
epi nou jis di n paske ou gen
yo konpare chak nan these-- chak pè.

1224
00:51:31,680 --> 00:51:36,470
Se konsa, li ta n mwens 1, ki nou
nou ta jis di se apeprè n.

1225
00:51:36,470 --> 00:51:39,280
Lè ou ap fè fas ak ègzekutabl,
tout bagay se nan apwoksimasyon.

1226
00:51:39,280 --> 00:51:43,860
Osi lontan ke ekspozan an se
kòrèk, w ap trè bon.

1227
00:51:43,860 --> 00:51:45,700
>> Sa a ki jan nou fè fas ak li.

1228
00:51:45,700 --> 00:51:47,410

1229
00:51:47,410 --> 00:51:51,780
Se konsa, ki ka ki pi bon se n, ki
vle di ke se lis la deja klase,

1230
00:51:51,780 --> 00:51:54,320
ak tout sa nou fè se kouri nan
epi tcheke ke li nan Ranje.

1231
00:51:54,320 --> 00:51:56,110

1232
00:51:56,110 --> 00:51:56,855
Fre.

1233
00:51:56,855 --> 00:51:57,355
Tout dwa.

1234
00:51:57,355 --> 00:51:58,980

1235
00:51:58,980 --> 00:52:01,920
Se konsa, kòm ou wè la a, nou
jis gen kèk grafik plis.

1236
00:52:01,920 --> 00:52:02,660
Se konsa, n okib.

1237
00:52:02,660 --> 00:52:03,780

1238
00:52:03,780 --> 00:52:05,120
Fun.

1239
00:52:05,120 --> 00:52:09,730
Anpil pi mal pase n jan nou wè, ak
anpil, anpil pi mal pase boutèy demi lit 2n.

1240
00:52:09,730 --> 00:52:12,060
Lè sa a, ou jwenn tou nan boutèy demi lit mòso bwa.

1241
00:52:12,060 --> 00:52:18,020
Epi ou pran 124, ou jwenn yo nan
tankou zetwal boutèy demi lit, ki se tankou fou.

1242
00:52:18,020 --> 00:52:20,172
Se konsa, si w ap enterese,
Passage boutèy demi lit zetwal.

1243
00:52:20,172 --> 00:52:20,880
Li nan kalite plezi.

1244
00:52:20,880 --> 00:52:22,800

1245
00:52:22,800 --> 00:52:24,220
Se konsa, nou gen gwo tablo sa a.

1246
00:52:24,220 --> 00:52:25,360

1247
00:52:25,360 --> 00:52:28,720
Jis yon chèf moute, sa a yon
bèl bagay tablo yo gen

1248
00:52:28,720 --> 00:52:31,350
pou ou mitan-tèm paske nou
long yo mande w thins sa yo.

1249
00:52:31,350 --> 00:52:36,090
Se konsa, jis yon tèt moute yo, yo gen sa a sou ou
mitan-tèm sou fèy bèl twonpe ou

1250
00:52:36,090 --> 00:52:36,616
gen.

1251
00:52:36,616 --> 00:52:37,990
Se konsa, nou jis gade sòt jarèt.

1252
00:52:37,990 --> 00:52:39,510

1253
00:52:39,510 --> 00:52:42,370
Pi move ka, n okib, pi bon ka, n.

1254
00:52:42,370 --> 00:52:43,367

1255
00:52:43,367 --> 00:52:44,950
E nou pral fè yon gade nan lòt moun yo.

1256
00:52:44,950 --> 00:52:47,940
>> Ak jan ou ka wè sèlman an,
youn ki vrèman fè byen

1257
00:52:47,940 --> 00:52:50,910
se sòt unifye, ki nou pral jwenn nan pou ki rezon.

1258
00:52:50,910 --> 00:52:52,690

1259
00:52:52,690 --> 00:52:55,215
Se konsa, nou ap ale nan ale nan la
pwochen youn isit lan-- sòt seleksyon an.

1260
00:52:55,215 --> 00:52:56,360

1261
00:52:56,360 --> 00:52:58,420
nenpòt moun ki sonje ki jan
seleksyon sòt te travay?

1262
00:52:58,420 --> 00:53:05,200

1263
00:53:05,200 --> 00:53:05,700
Ale pou li.

1264
00:53:05,700 --> 00:53:08,210
>> ELÈV: Fondamantalman ale nan
yon lòd pou ak kreye yon lis nouvo.

1265
00:53:08,210 --> 00:53:11,001
Ak jis kòm w ap mete eleman
nan, mete yo nan plas la dwat

1266
00:53:11,001 --> 00:53:11,750
nan lis la nouvo.

1267
00:53:11,750 --> 00:53:14,040
>> Enstriktè: Se konsa, ki son
plis tankou sòt ensèsyon.

1268
00:53:14,040 --> 00:53:15,040
Men, w ap reyèlman fèmen.

1269
00:53:15,040 --> 00:53:15,915
Yo ap trè sanblab.

1270
00:53:15,915 --> 00:53:17,440
Menm mwen jwenn yo melanje moute pafwa.

1271
00:53:17,440 --> 00:53:18,981
Anvan seksyon sa a Mwen te tankou, rete tann.

1272
00:53:18,981 --> 00:53:20,130

1273
00:53:20,130 --> 00:53:20,630
OK.

1274
00:53:20,630 --> 00:53:24,141
Se konsa, sa ou vle
fè se sòt seleksyon,

1275
00:53:24,141 --> 00:53:25,890
wout la ou ka panse
sou li ak wout la

1276
00:53:25,890 --> 00:53:30,140
Mwen asire yo ke mwen eseye pa jwenn
yo melanje moute, se li ale nan

1277
00:53:30,140 --> 00:53:33,280
epi li chwazi a
pi piti nimewo ak li

1278
00:53:33,280 --> 00:53:36,070
mete ki nan kòmansman an nan lis ou a.

1279
00:53:36,070 --> 00:53:37,730
Li echanj l 'ak ke premye plas.

1280
00:53:37,730 --> 00:53:42,600

1281
00:53:42,600 --> 00:53:45,370
Yo aktyèlman gen yon egzanp pou mwen.

1282
00:53:45,370 --> 00:53:46,540
Awesome.

1283
00:53:46,540 --> 00:53:50,130
Se konsa, jis yon fason yo panse a seleksyon l--
sòt, chwazi valè a pi piti a.

1284
00:53:50,130 --> 00:53:51,940
Epi nou ap ale nan
kouri nan yon egzanp

1285
00:53:51,940 --> 00:53:55,320
ke mwen panse ke pral ede paske
Mwen panse ke vizyèl toujou ede.

1286
00:53:55,320 --> 00:53:58,510
Se konsa, nou kòmanse soti ak yon bagay
ki se konplètman klase.

1287
00:53:58,510 --> 00:54:00,730
Wouj yo pral klase,
vèt ap dwe klase.

1288
00:54:00,730 --> 00:54:02,190
Li pral tout fè sans nan yon dezyèm fwa.

1289
00:54:02,190 --> 00:54:08,950
>> Se konsa, nou ale nan epi nou repekte
depi nan konmansman an nan fen an.

1290
00:54:08,950 --> 00:54:12,320
Epi nou di, OK, 2 se
pi piti nimewo nou an.

1291
00:54:12,320 --> 00:54:15,680
Se konsa, nou ap ale nan pran 2 epi nou ap ale
pou avanse pou li nan devan nan etalaj nou an

1292
00:54:15,680 --> 00:54:17,734
paske li nan la
pi piti nimewo nou genyen.

1293
00:54:17,734 --> 00:54:19,150
Se konsa, se sa ki sa a ap fè isit la.

1294
00:54:19,150 --> 00:54:20,820
Li nan jis pral swap sa yo de.

1295
00:54:20,820 --> 00:54:21,850

1296
00:54:21,850 --> 00:54:25,450
Se konsa, kounye a nou gen yon Ranje
pati ak yon pati klase.

1297
00:54:25,450 --> 00:54:27,810
Ak sa ki nan bon sonje
sou sòt seleksyon

1298
00:54:27,810 --> 00:54:30,690
se nou ap sèlman chwazi
soti nan pati nan triye.

1299
00:54:30,690 --> 00:54:32,220

1300
00:54:32,220 --> 00:54:34,527
>> Pati nan Ranje ou jis kite pou kont li.

1301
00:54:34,527 --> 00:54:35,660
Milimèt-HM?

1302
00:54:35,660 --> 00:54:38,452
>> ELÈV: Ki jan li konnen ki sa ki
pi piti a san yo pa konpare li

1303
00:54:38,452 --> 00:54:39,868
tout lòt valè nan etalaj la.

1304
00:54:39,868 --> 00:54:41,250
Enstriktè: Li fè sa konpare li.

1305
00:54:41,250 --> 00:54:42,041
Nou renmen sote li.

1306
00:54:42,041 --> 00:54:43,850
Sa a se jis jeneral an jeneral.

1307
00:54:43,850 --> 00:54:44,831
Yeah.

1308
00:54:44,831 --> 00:54:47,205
Lè nou ekri kòd la mwen se
asire w ou pral gen plis satisfè.

1309
00:54:47,205 --> 00:54:48,696

1310
00:54:48,696 --> 00:54:53,030
Men, ou sere sa a premye
eleman kòm pi piti a.

1311
00:54:53,030 --> 00:54:56,110
Ou konpare epi ou
di, OK, se li ki pi piti?

1312
00:54:56,110 --> 00:54:56,660
Wi.

1313
00:54:56,660 --> 00:54:57,460
Kenbe li.

1314
00:54:57,460 --> 00:54:58,640
Isit la se li ki pi piti?

1315
00:54:58,640 --> 00:54:59,660
Pa gen?

1316
00:54:59,660 --> 00:55:02,510
>> Sa a se pi piti ou a,
mute li nan valè ou.

1317
00:55:02,510 --> 00:55:06,340
Men, ou pral pi kontan
lè nou ale nan kòd la.

1318
00:55:06,340 --> 00:55:07,510

1319
00:55:07,510 --> 00:55:13,970
Se konsa, nou ale nan, nou boukante li, se konsa Lè sa a,
nou gade nan sa a pòsyon klase.

1320
00:55:13,970 --> 00:55:15,810
Se konsa, nou ap ale nan chwazi twa deyò.

1321
00:55:15,810 --> 00:55:18,890
Nou pral mete l 'sou nan
nan fen pòsyon Ranje nou an.

1322
00:55:18,890 --> 00:55:20,267

1323
00:55:20,267 --> 00:55:23,100
Apre sa, nou ap jis ale nan kontinye ap fè
sa, fè sa, ak fè sa.

1324
00:55:23,100 --> 00:55:24,130

1325
00:55:24,130 --> 00:55:27,420
Se konsa, sa a se kalite nou an nan pseudocode isit la.

1326
00:55:27,420 --> 00:55:29,470

1327
00:55:29,470 --> 00:55:31,380
Nou pral Kòd li moute isit la nan yon dezyèm fwa.

1328
00:55:31,380 --> 00:55:34,140

1329
00:55:34,140 --> 00:55:37,270
Men, jis yon bagay yo mache
a sou yon nivo segondè.

1330
00:55:37,270 --> 00:55:40,275
W ap ale nan ale nan
mwen egal 0 a n mwens 2.

1331
00:55:40,275 --> 00:55:41,570

1332
00:55:41,570 --> 00:55:43,530
Sa a yon lòt optimize.

1333
00:55:43,530 --> 00:55:45,020
pa enkyete twòp sou li.

1334
00:55:45,020 --> 00:55:46,620
Se konsa, kòm ou te di.

1335
00:55:46,620 --> 00:55:49,660

1336
00:55:49,660 --> 00:55:54,406
Kòm Jakòb te di: ki jan nou
kenbe tras nan sa minimòm nou an, se?

1337
00:55:54,406 --> 00:55:55,030
Kouman nou fè konnen?

1338
00:55:55,030 --> 00:55:57,060
Nou gen yo konpare
tout bagay nan lis nou an.

1339
00:55:57,060 --> 00:55:59,600
>> Se konsa, minimòm egal mwen.

1340
00:55:59,600 --> 00:56:03,870
Li nan jis li di nan ka sa a
endèks la nan valè minimòm nou an.

1341
00:56:03,870 --> 00:56:07,660
Se konsa, Lè sa a, li nan ale nan repekte nan
epi li ale soti nan j egal mwen plis 1.

1342
00:56:07,660 --> 00:56:11,420
Se konsa, nou deja konnen ke
sa a, se eleman premye nou an.

1343
00:56:11,420 --> 00:56:13,240
Nou pa bezwen li konpare l ak tèt li.

1344
00:56:13,240 --> 00:56:16,970
Se konsa, nou kòmanse konpare li nan pwochen an
yon sèl ki se poukisa li a mwen plis 1 a n

1345
00:56:16,970 --> 00:56:20,110
mwens 1, ki se nan
fen nan etalaj la a.

1346
00:56:20,110 --> 00:56:25,090
Apre sa, nou te di si etalaj nan
j se mwens pase etalaj min,

1347
00:56:25,090 --> 00:56:29,200
lè sa a nou mute kote
endis minimòm nou an, se.

1348
00:56:29,200 --> 00:56:37,470
>> Men, si min se pa egal a mwen, kòm
nan kote nou te tounen sou isit la.

1349
00:56:37,470 --> 00:56:38,950

1350
00:56:38,950 --> 00:56:41,790
Se konsa, renmen lè nou premye te fè sa a yon sèl.

1351
00:56:41,790 --> 00:56:49,310
Nan ka sa a, li ta kòmanse nan
zewo, li ta yo te fini de.

1352
00:56:49,310 --> 00:56:53,010
Se konsa, min pa ta egal mwen nan fen an.

1353
00:56:53,010 --> 00:56:55,720
Sa pèmèt nou konnen ke
nou bezwen swap yo.

1354
00:56:55,720 --> 00:56:57,420

1355
00:56:57,420 --> 00:57:00,470
Mwen santi mwen tankou yon egzanp konkrè
pral ede pi plis pase sa a.

1356
00:57:00,470 --> 00:57:04,970
Se konsa, mwen pral Kòd sa a moute ak ou nèg
kounye a epi mwen panse ke li pral pi byen.

1357
00:57:04,970 --> 00:57:07,380

1358
00:57:07,380 --> 00:57:11,350
>> Kalite yo gen tandans travay ki fason nan ki
li souvan pi bon jis yo wè yo.

1359
00:57:11,350 --> 00:57:12,780

1360
00:57:12,780 --> 00:57:17,280
Se konsa, ki sa nou vle fè se
nou vle premye pi piti a

1361
00:57:17,280 --> 00:57:19,890
eleman nan pozisyon li nan etalaj la.

1362
00:57:19,890 --> 00:57:21,280
Ekzakteman ki sa Jakòb te di.

1363
00:57:21,280 --> 00:57:23,090
Ou bezwen nan magazen ki yon jan kanmenm.

1364
00:57:23,090 --> 00:57:25,900
Se konsa, nou ap ale nan kòmanse isit la
iteration sou etalaj la.

1365
00:57:25,900 --> 00:57:28,970
Nou pral di li nan nou an
premye yon sèl jis yo kòmanse avèk yo.

1366
00:57:28,970 --> 00:57:38,308
Se konsa, nou yo ale nan gen int
pi piti ki egal a etalaj nan mwen.

1367
00:57:38,308 --> 00:57:40,500

1368
00:57:40,500 --> 00:57:45,050
>> Se konsa, yon sèl bagay a yon avi, chak
tan sa a riban ègzekutra,

1369
00:57:45,050 --> 00:57:48,550
nou ap kòmanse yon sèl etap plis ansanm.

1370
00:57:48,550 --> 00:57:54,780

1371
00:57:54,780 --> 00:57:57,440
Lè nou kòmanse nou gade nan yon sèl sa a.

1372
00:57:57,440 --> 00:58:00,840
Tan nan pwochen nou repekte nan,
nou ap kòmanse nan yon sèl sa a

1373
00:58:00,840 --> 00:58:02,680
ak plase li pi piti valè nou yo.

1374
00:58:02,680 --> 00:58:10,450
Se konsa, li trè menm jan ak sòt jarèt
kote nou konnen ke apre yon pas,

1375
00:58:10,450 --> 00:58:11,700
se sa a eleman dènye Ranje.

1376
00:58:11,700 --> 00:58:12,810

1377
00:58:12,810 --> 00:58:15,120
Avèk sòt seleksyon,
li nan jis opoze an.

1378
00:58:15,120 --> 00:58:18,950
>> Nan chak pas, nou konnen ke
se youn nan premye Ranje.

1379
00:58:18,950 --> 00:58:21,360
Apre pas, dezyèm lan, nan
pral dezyèm yon sèl dwe klase.

1380
00:58:21,360 --> 00:58:26,470
Ak jan ou te wè ak egzanp yo glise,
pòsyon Ranje nou an jis kenbe k ap grandi.

1381
00:58:26,470 --> 00:58:34,020
Se konsa, pa mete pi piti yon sèl nou an
ranje mwen, tout li nan fè

1382
00:58:34,020 --> 00:58:37,340
se konprime sa
nou ap chèche a se konsa yo

1383
00:58:37,340 --> 00:58:40,164
pou misyon pou minimize kantite a
nan konparezon nou fè.

1384
00:58:40,164 --> 00:58:41,770
ki fè sans a tout moun?

1385
00:58:41,770 --> 00:58:42,920

1386
00:58:42,920 --> 00:58:46,380
Èske ou bezwen m 'nan kouri nan ki
ankò pi dousman oswa nan mo diferan?

1387
00:58:46,380 --> 00:58:47,180
Mwen kontan.

1388
00:58:47,180 --> 00:58:48,095

1389
00:58:48,095 --> 00:58:48,595
OK.

1390
00:58:48,595 --> 00:58:50,060

1391
00:58:50,060 --> 00:58:55,540
>> Se konsa, nou ap estoke nan
valè nan pwen sa a,

1392
00:58:55,540 --> 00:58:57,840
men nou menm tou nou vle nan magazen endèks la.

1393
00:58:57,840 --> 00:59:01,010
Se konsa, nou ap ale nan magazen an
pozisyon nan pi piti a

1394
00:59:01,010 --> 00:59:02,770
yon sèl, ki se jis pral fè mwen.

1396
00:59:04,357 --> 00:59:05,440
Se konsa, kounye Jakòb se satisfè.

1397
00:59:05,440 --> 00:59:06,870
Nou gen bagay sa yo ki estoke.

1398
00:59:06,870 --> 00:59:08,240

1399
00:59:08,240 --> 00:59:11,870
Epi, koulye a nou bezwen gade nan
pati nan triye nan etalaj la.

1400
00:59:11,870 --> 00:59:18,170
Se konsa, nan ka sa a sa a
ta dwe klase nou an.

1401
00:59:18,170 --> 00:59:20,980

1402
00:59:20,980 --> 00:59:22,462
Sa a se mwen.

00:59:22,462 --> 00:59:25,430

1404
00:59:25,430 --> 00:59:26,210
OK.

1405

>> Se konsa, ki sa nou ap ale nan fè
a pwal pou yon riban.

1406

Chak fwa ou bezwen
repekte nan yon etalaj,

1407
00:59:32,066 --> 00:59:33,440
lide ou te ka ale nan pou yon riban.

1408
00:59:33,440 --> 00:59:34,760

1409
00:59:34,760 --> 00:59:38,090
Se konsa, pou kèk k Int
equals-- sa nou panse

1410
00:59:38,090 --> 00:59:39,700
k ki pral egal a kòmanse ak?

1411
00:59:39,700 --> 00:59:41,580

1412
00:59:41,580 --> 00:59:44,766
Sa a se ki sa nou mete kòm pi piti nou an
valè ak nou vle konpare li.

1413
00:59:44,766 --> 00:59:47,090
Ki sa nou vle konpare li a?

1414
00:59:47,090 --> 00:59:48,730
Li nan ale nan fè yon sèl sa a kap vini an, dwa?

1415
00:59:48,730 --> 00:59:53,200
Se konsa, nou vle k yo dwe inisyalizèd
mwen plis 1 yo kòmanse.

1416
00:59:53,200 --> 00:59:55,350

1417

>> E nou vle k nan ka sa a nou
deja te gwosè estoke moute isit la,

1418
01:00:02,800 --> 01:00:03,930
pou nou ka jis itilize gwosè.

1419
01:00:03,930 --> 01:00:06,240
Size ke yo te gwosè a nan etalaj la.

1420
01:00:06,240 --> 01:00:09,620
Apre sa, nou jis vle
aktyalizasyon k pa youn chak fwa.

1421
01:00:09,620 --> 01:00:17,410

1424
01:00:19,650 --> 01:00:23,430
Se konsa, kounye a nou bezwen jwenn
eleman ki pi piti isit la.

01:00:23,430 --> 01:00:24,470

1426
01:00:24,470 --> 01:00:31,380
Se konsa, si nou repekte nan, nou
vle di, si etalaj nan k

1427
01:00:31,380 --> 01:00:37,080
se mwens pase pi piti value-- nou an
sa a se kote nou ap aktyèlman

kenbe tras nan sa ki nan
isit lan-- ki pi piti a

1429
01:00:42,950 --> 01:00:47,740
Lè sa a, nou vle mute
sa pi piti valè nou an, se.

1430
01:00:47,740 --> 01:00:50,645
>> Sa vle di ke, o, nou ap
iteration nan isit la.

01:00:54,448 --> 01:00:56,100
Nou vle mute li.

1435
01:00:56,100 --> 01:01:02,050
Se konsa, si nou ap reafèktasyon li, sa ki fè
ou panse ta ka nan sa a kòd isit la?

1436
01:01:02,050 --> 01:01:04,160
Nou vle mute
pi piti ak pozisyon.

01:08:34,910 --> 01:08:39,270
gen yon lis konplètman Ranje
ki kote klase se kounye a zewo

1611
01:08:39,270 --> 01:08:41,720
ak Ranje pran moute nan
antye nan lis nou an.

1612
01:08:41,720 --> 01:08:43,146

1613
01:08:43,146 --> 01:08:45,854
Se konsa, ankò, fè bagay sa yo menm
plis konkrè, nou gen pseudocode.

1614
01:08:45,854 --> 01:08:47,979

1615
01:08:47,979 --> 01:08:52,410
>> Se konsa, fondamantalman pou mwen se
egal a 0 a n mwens 1,

1616
01:08:52,410 --> 01:08:54,790
sa se sèlman longè a nan etalaj nou an.

1617
01:08:54,790 --> 01:09:00,979
Nou gen kèk eleman ki ki egal a
etalaj la premye oswa endis yo an premye.

1618
01:09:00,979 --> 01:09:03,200
Nou mete j egal a sa.

1619
01:09:03,200 --> 01:09:04,649

1620
01:09:04,649 --> 01:09:09,210
Se konsa, pandan j pi gran pase
zewo ak etalaj, j nan mwens 1

1621
01:09:09,210 --> 01:09:11,660
gen plis pouvwa pase a
eleman, se konsa tout sa ki nan ap fè

1622
01:09:11,660 --> 01:09:17,479
se fè si ke
j ou reyèlman reprezante

1623
01:09:17,479 --> 01:09:20,010
pòsyon ki klase nan etalaj la.

1624
01:09:20,010 --> 01:09:30,745
>> Se konsa, pandan gen se toujou bagay
sòt ak yon j mwens is-- sa

1625
01:09:30,745 --> 01:09:31,840
se eleman ki li?

1626
01:09:31,840 --> 01:09:34,760
J pa te janm defini isit la.

1627
01:09:34,760 --> 01:09:35,677
Li nan kalite anmèdan.

1628
01:09:35,677 --> 01:09:36,176
OK.

1629
01:09:36,176 --> 01:09:36,689
Aniwe.

1630
01:09:36,689 --> 01:09:39,899
Se konsa, j mwens 1, w ap tcheke
eleman nan anvan li.

1631
01:09:39,899 --> 01:09:46,460
Ou ap di, OK, se eleman ki
anvan tout kote mwen am-- kite nan

1632
01:09:46,460 --> 01:09:47,540
aktyèlman trase sa a soti.

1633
01:09:47,540 --> 01:09:52,580

1634
01:09:52,580 --> 01:09:56,830
Se konsa nou di sa a se
tankou sou dezyèm pas nou an.

1635
01:09:56,830 --> 01:09:59,525
Se konsa, mwen a pwal egal
nan 1, ki se isit la.

1636
01:09:59,525 --> 01:10:03,310

1637
01:10:03,310 --> 01:10:06,025
>> Se konsa, mwen a pwal egal a 1.

1638
01:10:06,025 --> 01:10:09,510

1639
01:10:09,510 --> 01:10:13,702
Sa a ta dwe 2, 4, 5, 6, 7.

1640
01:10:13,702 --> 01:10:16,060

1641
01:10:16,060 --> 01:10:16,750
Tout dwa.

1642
01:10:16,750 --> 01:10:20,945
Se konsa, eleman nou an nan ka sa a
a pwal egal a 4.

1643
01:10:20,945 --> 01:10:22,110

1644
01:10:22,110 --> 01:10:24,946
Epi nou gen kèk j sa a, se
ale nan dwe egal a 1.

1645
01:10:24,946 --> 01:10:29,770

1646
01:10:29,770 --> 01:10:30,971
Oh, j se decrementing.

1647
01:10:30,971 --> 01:10:31,720
Sa a ki sa li ye.

1648
01:10:31,720 --> 01:10:35,680
Se konsa, j ki egal a mwen, se konsa sa sa a se
li di se ke jan nou avanse pou pi devan,

1649
01:10:35,680 --> 01:10:37,530
nou ap jis fè si
ke nou pa ap sou

1650
01:10:37,530 --> 01:10:43,520
Indexing fason sa a lè nou ap eseye
insert bagay sa yo nan lis Ranje nou an.

1651
01:10:43,520 --> 01:10:49,850
>> Se konsa, lè j ki egal a 1 nan ka sa a ak
etalaj j mwens one-- konsa 1 etalaj j mwens

1652
01:10:49,850 --> 01:10:54,610
se 2 nan case-- sa a si sa a
pi gran pase eleman nan,

1653
01:10:54,610 --> 01:10:57,700
Lè sa a, tout bagay sa a ap fè
se deplasman bagay sa yo desann.

1654
01:10:57,700 --> 01:11:04,790
Se konsa, nan ka sa a, etalaj j mwens yon sèl
ta dwe etalaj zewo, ki se 2.

1655
01:11:04,790 --> 01:11:08,430
2 se pa janm pi grannèg pase 4,
se konsa sa a pa egzekite.

1656
01:11:08,430 --> 01:11:11,460
Se konsa, chanjman nan pa deplase desann.

1657
01:11:11,460 --> 01:11:18,790
Ki sa sa fè isit la se jis
k ap deplase etalaj Ranje ou desann.

1658
01:11:18,790 --> 01:11:22,340

1659
01:11:22,340 --> 01:11:26,400
Nan ka sa a, aktyèlman, nou
te kapab do-- kite a fè sa a 3.

1660
01:11:26,400 --> 01:11:28,080

1661
01:11:28,080 --> 01:11:31,970
Se konsa, si nou ap mache nan ak
egzanp sa a, nou ap kounye a isit la.

1662
01:11:31,970 --> 01:11:32,740
Sa a se Klase.

1663
01:11:32,740 --> 01:11:34,492

1664
01:11:34,492 --> 01:11:35,200
Sa a se klase.

1665
01:11:35,200 --> 01:11:39,090

1666
01:11:39,090 --> 01:11:39,860
Cool?

1667
01:11:39,860 --> 01:11:46,620
Se konsa, mwen ki egal a 2, se konsa
eleman nou an ki egal a 3.

1668
01:11:46,620 --> 01:11:47,920

1669
01:11:47,920 --> 01:11:52,270
Epi j nou an ki egal a 2.

1670
01:11:52,270 --> 01:12:00,620
Se konsa, nou gade nan epi nou
di, OK, se youn etalaj j mwens

1671
01:12:00,620 --> 01:12:03,470
pi gran pase eleman nan
ke nou ap chèche a?

1672
01:12:03,470 --> 01:12:05,540
Ak repons lan se wi, dwa?

1673
01:12:05,540 --> 01:12:11,275
4 pi gran pase 3 ak j
se 2, se konsa sa a kòd ègzekutra.

1674
01:12:11,275 --> 01:12:12,510

1675
01:12:12,510 --> 01:12:18,550
>> Se konsa, kounye a ki sa nou fè yon etalaj nan
2, se konsa dwa isit la, nou boukante yo.

1676
01:12:18,550 --> 01:12:25,620
Se konsa, nou jis di, OK, etalaj
nan 2 se kounye a pral fè 3.

1677
01:12:25,620 --> 01:12:28,130

1678
01:12:28,130 --> 01:12:32,340
Epi j ki pral egal
j mwens 1, ki se 1.

1679
01:12:32,340 --> 01:12:34,590

1680
01:12:34,590 --> 01:12:37,200
Sa a terib, men
ou nèg jwenn lide la.

1681
01:12:37,200 --> 01:12:38,360
J se kounye a egal a 1.

1682
01:12:38,360 --> 01:12:44,360
Ak etalaj j se jis ale nan gen
egal a eleman nou an, ki te 4.

1683
01:12:44,360 --> 01:12:45,950

1684
01:12:45,950 --> 01:12:48,570
Mwen efasman yon bagay mwen pa ta dwe
genyen oswa miswrote yon bagay,

1685
01:12:48,570 --> 01:12:49,910
men ou nèg jwenn lide la.

1686
01:12:49,910 --> 01:12:50,640
>> Li deplase nan n.

1687
01:12:50,640 --> 01:12:51,920

1688
01:12:51,920 --> 01:12:57,960
Lè sa a, si sa a yo te, li ta bouk
ankò epi li ta di, OK, j se 1 kounye a.

1689
01:12:57,960 --> 01:13:00,665
Ak etalaj j mwens 1 se kounye a 2.

1690
01:13:00,665 --> 01:13:01,750

1691
01:13:01,750 --> 01:13:03,760
Se 2 pi piti pase eleman nou an?

1692
01:13:03,760 --> 01:13:04,540
Pa gen?

1693
01:13:04,540 --> 01:13:07,970
Sa vle di ke nou te
eleman sa a eleman

1694
01:13:07,970 --> 01:13:10,110
nan plas ki kòrèk la nan etalaj Ranje nou an.

1695
01:13:10,110 --> 01:13:14,400
Lè sa a, nou ka pran sa a epi nou di,
OK, etalaj Ranje nou an se isit la.

1696
01:13:14,400 --> 01:13:19,940
Epi li ta pran nimewo sa a 6 epi yo dwe
tankou, OK, se 6 mwens pase kantite sa a?

1697
01:13:19,940 --> 01:13:20,480
Pa gen?

1698
01:13:20,480 --> 01:13:21,080
Fre.

1699
01:13:21,080 --> 01:13:22,680
Nou amann.

1700
01:13:22,680 --> 01:13:23,530
>> Èske l 'ankò.

1701
01:13:23,530 --> 01:13:24,740
Nou di 7.

1702
01:13:24,740 --> 01:13:29,010
Se 7 mwens pase fen a
nan etalaj Ranje nou an?

1703
01:13:29,010 --> 01:13:29,520
No

1704
01:13:29,520 --> 01:13:30,430
Se konsa, nou ap amann.

1705
01:13:30,430 --> 01:13:32,760
Se konsa, sa a ta dwe klase.

1706
01:13:32,760 --> 01:13:38,610
Fondamantalman tout bagay sa a fè
se li nan di pran

1707
01:13:38,610 --> 01:13:42,060
eleman nan premye nan
etalaj klase ou,

1708
01:13:42,060 --> 01:13:46,010
konnen ki kote li ale
nan etalaj Ranje ou yo.

1709
01:13:46,010 --> 01:13:48,780
Lè sa a jis pran swen
nan echanj fè sa.

1710
01:13:48,780 --> 01:13:51,300
W ap fondamantalman jis échanjé
jouk li a nan plas la dwat.

1711
01:13:51,300 --> 01:13:53,600

1712
01:13:53,600 --> 01:13:56,990
Imaj la vizyèl se ke w ap
k ap deplase tout bagay desann nan fè sa.

1713
01:13:56,990 --> 01:13:59,420
>> Se konsa, li la tankou mwatye ti wonn sòt-esque.

1714
01:13:59,420 --> 01:14:02,280

1715
01:14:02,280 --> 01:14:03,420
Tcheke etid 50.

1716
01:14:03,420 --> 01:14:06,000
Mwen trè rekòmande ap eseye
nan kòd sa a sou pwòp ou yo.

1717
01:14:06,000 --> 01:14:07,220

1718
01:14:07,220 --> 01:14:12,450
Si w gen nenpòt pwoblèm oswa ou vle
wè echantiyon Kòd pou yon sòt ensèsyon,

1719
01:14:12,450 --> 01:14:13,750
tanpri kite m 'konnen.

1720
01:14:13,750 --> 01:14:14,500
Mwen toujou alantou.

1721
01:14:14,500 --> 01:14:16,600

1722
01:14:16,600 --> 01:14:20,200
Se konsa, pi mal la ègzekutabl ka
ak pi bon ègzekutabl ka.

1723
01:14:20,200 --> 01:14:30,700
Kòm ou te wè nèg soti bò tab la mwen deja
te montre ou, li nan tou de n okib ak n.

1724
01:14:30,700 --> 01:14:35,590
>> Se konsa, jan de pral koupe nan sa ki nou te pale
sou ak kalite anvan yo nou an, pi move

1725
01:14:35,590 --> 01:14:38,760
ka ègzekutabl se ke si
li nan konplètman klase,

1726
01:14:38,760 --> 01:14:42,530
nou gen yo konpare tout nan fwa n sa yo.

1727
01:14:42,530 --> 01:14:47,020
Nou fè yon anpil tout konparezon
paske si li nan nan do lòd,

1728
01:14:47,020 --> 01:14:50,360
nou ap ale nan di, OK, sa a
se menm bagay la, sa a se yon bon bagay,

1729
01:14:50,360 --> 01:14:54,650
ak yon sèl sa a pral gen ka konpare
kont youn nan premye yo dwe deplase tounen.

1730
01:14:54,650 --> 01:14:56,710
E kòm nou jwenn nan direksyon
fen a ke, nou gen

1731
01:14:56,710 --> 01:14:59,440
yo konpare, konpare, ak
konpare kont tout bagay.

1732
01:14:59,440 --> 01:15:03,030
>> Se konsa, li fini moute yo te
apeprè n okib.

1733
01:15:03,030 --> 01:15:09,510
Si li nan kòrèk lè sa a ou
di, OK, 2, w ap bon.

1734
01:15:09,510 --> 01:15:11,330
3, w ap konpare ak 2.

1735
01:15:11,330 --> 01:15:12,310
Ou se bon.

1736
01:15:12,310 --> 01:15:14,150
4, ou jis konpare ak ke la.

1737
01:15:14,150 --> 01:15:14,990
Ou se bon.

1738
01:15:14,990 --> 01:15:17,140
6, konpare ak ke a, w ap amann.

1739
01:15:17,140 --> 01:15:20,870
Se konsa, pou chak plas si li nan deja
Ranje, ou ap fè yon sèl konparezon.

1740
01:15:20,870 --> 01:15:22,320
Se konsa, li nan jis n.

1741
01:15:22,320 --> 01:15:26,840
Epi paske nou gen yon ègzekutabl ka pi bon
nan n ak yon ègzekutabl ka pi mal la nan n

1742
01:15:26,840 --> 01:15:28,680
okib, nou pa gen okenn ègzekutabl atann.

1743
01:15:28,680 --> 01:15:31,290

1744
01:15:31,290 --> 01:15:34,020
>> Li jis depann sou la
dezòd nan lis nou an la.

1745
01:15:34,020 --> 01:15:35,860

1746
01:15:35,860 --> 01:15:39,530
Epi ankò, yon lòt
graf ak yon lòt tab.

1747
01:15:39,530 --> 01:15:41,170
Se konsa, diferans ki genyen ant kalite.

1748
01:15:41,170 --> 01:15:44,180
Mwen jis ale nan briz atravè, mwen
santi tankou nou te pale anpil

1749
01:15:44,180 --> 01:15:46,570
sou fason yo tout kalite
a varye ak lyen yo ansanm.

1750
01:15:46,570 --> 01:15:50,564
Se konsa, rantre sòt se youn nan dènye
M pral fè ou nèg ak.

1751
01:15:50,564 --> 01:15:52,105
Nou gen yon foto bèl kolore.

1752
01:15:52,105 --> 01:15:53,860

1753
01:15:53,860 --> 01:15:56,040
Se konsa, rantre sòt se yon algorithm repetitif.

1754
01:15:56,040 --> 01:15:59,910
Se konsa, ou nèg konnen ki sa
yon fonksyon repetitif se?

1755
01:15:59,910 --> 01:16:01,550

1756
01:16:01,550 --> 01:16:03,320
>> Nenpòt moun ki vle di?

1757
01:16:03,320 --> 01:16:04,739
Ou vle eseye?

1758
01:16:04,739 --> 01:16:07,280
Se konsa, yon fonksyon repetitif se jis
yon fonksyon ki rele tèt li.

1759
01:16:07,280 --> 01:16:08,570

1760
01:16:08,570 --> 01:16:11,590
Se konsa, si ou nèg yo abitye
ak sekans lan Fibonacci,

1761
01:16:11,590 --> 01:16:15,670
ki nan jije repetitif paske
ou pran de la anvan yo

1762
01:16:15,670 --> 01:16:17,530
epi ajoute yo ansanm
yo jwenn youn pwochèn ou an.

1763
01:16:17,530 --> 01:16:21,440
Se konsa, repetitif, mwen toujou panse
nan rkursyon kòm tankou yon espiral

1764
01:16:21,440 --> 01:16:24,430
se konsa w ap tankou espiral desann nan li.

1765
01:16:24,430 --> 01:16:27,150
Men, li la jis yon fonksyon
ki rele tèt li.

1766
01:16:27,150 --> 01:16:32,660
>> Epi, aktyèlman, vrèman byen vit Mwen
ka montre w ki sa sa sanble.

1767
01:16:32,660 --> 01:16:34,260

1768
01:16:34,260 --> 01:16:41,840
Se konsa, isit la repetitif, si nou gade, sa a se
wout la repetitif ak sòm sou yon etalaj.

1769
01:16:41,840 --> 01:16:45,900

1770
01:16:45,900 --> 01:16:47,880
Se konsa, tout sa ki nou fè se
nou gen fonksyon sòm

1771
01:16:47,880 --> 01:16:52,210
sòm ki pran yon gwosè ak yon etalaj.

1772
01:16:52,210 --> 01:16:55,210
Men, si w remake, gwosè
dekremant pa youn chak fwa.

1773
01:16:55,210 --> 01:17:00,365
Apre sa, tout sa li fè se si x se egal a
zero-- Se konsa, si gwosè a nan etalaj la

1774
01:17:00,365 --> 01:17:02,710
ki egal a zero-- li retounen zewo.

1775
01:17:02,710 --> 01:17:10,440
>> Sinon li rezime sa a
eleman sot pase a nan etalaj la,

1776
01:17:10,440 --> 01:17:14,790
ak Lè sa a pran yon sòm de
rès la nan etalaj la.

1777
01:17:14,790 --> 01:17:17,555
Se konsa, li jis kraze li desann
nan pi piti ak pi piti pwoblèm.

1778
01:17:17,555 --> 01:17:18,990

1779
01:17:18,990 --> 01:17:21,890
Long istwa kout, rkursyon,
fonksyon ki rele tèt li.

1780
01:17:21,890 --> 01:17:25,740
Si sa a tout sa ou te resevwa soti nan sa a,
se sa ki yon fonksyon repetitif se.

1781
01:17:25,740 --> 01:17:29,870
Si ou pran 51, ou pral jwenn anpil,
trè alèz ak rkursyon.

1782
01:17:29,870 --> 01:17:31,110

1783
01:17:31,110 --> 01:17:32,370
Li nan vrèman fre.

1784
01:17:32,370 --> 01:17:34,660
Li te fè sans nan tankou
3 AM yon jou lannwit deyò.

1785
01:17:34,660 --> 01:17:37,900
Apre sa, mwen te tankou, poukisa
m 'pa janm sèvi ak sa a?

1786
01:17:37,900 --> 01:17:39,170

1787
01:17:39,170 --> 01:17:42,430
>> Se konsa, pou sòt unifye, fondamantalman
ki sa li la pral fè se li nan

1788
01:17:42,430 --> 01:17:45,620
ale nan kraze li desann ak kraze li
desann jouk li a eleman jis sèl.

1789
01:17:45,620 --> 01:17:47,570
Eleman yo yon sèl yo, yo fasil yo sòt.

1790
01:17:47,570 --> 01:17:48,070
Nou wè ke.

1791
01:17:48,070 --> 01:17:50,760
Si ou gen yon sèl eleman, li nan
deja konsidere kòm Ranje.

1792
01:17:50,760 --> 01:17:53,800
Se konsa, sou yon D 'nan eleman n,
si n se mwens pase 2,

1793
01:17:53,800 --> 01:17:58,120
jis retounen paske sa vle di
li nan swa 0 oswa 1 jan nou te wè.

1794
01:17:58,120 --> 01:18:00,050
Moun sa yo ki yo konsidere kòm eleman Ranje.

1795
01:18:00,050 --> 01:18:02,170
>> Sinon kraze li nan mwatye.

1796
01:18:02,170 --> 01:18:06,336
Sòt mwatye a an premye, dezyèm nan sòt
mwatye, ak Lè sa a, rantre yo ansanm.

1797
01:18:06,336 --> 01:18:07,460
Poukisa sa yo rele sòt unifye.

1798
01:18:07,460 --> 01:18:08,700

1799
01:18:08,700 --> 01:18:12,155
Se konsa, nou gen isit la nou pral sòt sa yo.

1800
01:18:12,155 --> 01:18:13,410

1801
01:18:13,410 --> 01:18:17,210
Se konsa, nou kenbe fè yo
jouk gwosè a etalaj se 1.

1802
01:18:17,210 --> 01:18:20,790
Se konsa, lè li nan 1, nou jis retounen
paske sa a se yon etalaj Ranje,

1803
01:18:20,790 --> 01:18:23,940
ak sa a se yon etalaj Ranje, epi ki nan
yon etalaj Ranje, nou ap tout Ranje.

1804
01:18:23,940 --> 01:18:25,390

1805
01:18:25,390 --> 01:18:29,420
Se konsa, Lè sa a, ki sa nou fè se nou
kòmanse fusion yo ansanm.

1806
01:18:29,420 --> 01:18:31,820
>> Se konsa, wout la ou kapab
panse osijè de fusion se

1807
01:18:31,820 --> 01:18:36,240
ou jis retire ki pi piti a
Nimewo nan chak nan ranje yo sub

1808
01:18:36,240 --> 01:18:38,330
ak jis kole li nan etalaj la parèt.

1809
01:18:38,330 --> 01:18:44,290
Se konsa, si ou gade isit la, lè nou gen
kouche sa yo nou gen 4, 6, ak 1.

1810
01:18:44,290 --> 01:18:47,280
Lè nou vle rantre sa yo,
nou gade nan sa yo de premye

1811
01:18:47,280 --> 01:18:50,730
epi nou di, OK, 1 se pi piti,
li ale nan devan an.

1812
01:18:50,730 --> 01:18:54,330
4 ak 6, pa gen anyen yo konpare
li nan, jis tag l 'sou nan fen an.

1813
01:18:54,330 --> 01:18:58,020
>> Lè nou konbine de sa yo, nou jis
pran youn ki pi piti a nan de sa yo,

1814
01:18:58,020 --> 01:18:59,310
se konsa li a 1.

1815
01:18:59,310 --> 01:19:01,690
Epi, koulye a nou pran an
ki pi piti nan sa yo de, se konsa 2.

1816
01:19:01,690 --> 01:19:03,330
Ki pi piti nan de sa yo, 3.

1817
01:19:03,330 --> 01:19:06,260
Ki pi piti nan sa yo de, 4, 5, 6.

1818
01:19:06,260 --> 01:19:08,630
Se konsa, w ap sèlman rale koupe sa yo.

1819
01:19:08,630 --> 01:19:11,210
Ak yo paske yo te gen
te Ranje deja,

1820
01:19:11,210 --> 01:19:14,300
ou jis gen yon sèl
konparezon chak fwa a.

1821
01:19:14,300 --> 01:19:19,610
Se konsa, plis Kòd isit la, jis reprezantasyon.

1822
01:19:19,610 --> 01:19:24,410
Se konsa, ou kòmanse nan mitan an ak
ou sòt kite la ak dwa nan

1823
01:19:24,410 --> 01:19:26,180
ak Lè sa a ou jis rantre sa yo.

1824
01:19:26,180 --> 01:19:30,080
>> Epi nou pa gen kòd
pou rantre dwa isit la.

1825
01:19:30,080 --> 01:19:34,110
Men, ankò, si ou ale sou
etidye 50, li pral dwe la.

1826
01:19:34,110 --> 01:19:36,860
Sinon vini pale ak m '
si w ap toujou konfonn.

1827
01:19:36,860 --> 01:19:42,340
Se konsa, bagay fre isit la se ke ka pi bon,
pi move ka, ak ègzekutabl espere

1828
01:19:42,340 --> 01:19:46,250
yo tout nan boutèy demi lit n, ki
se byen lwen pi bon pase nou te

1829
01:19:46,250 --> 01:19:48,000
wè pou rès la nan kalite nou an.

1830
01:19:48,000 --> 01:19:51,840
Nou te wè n okib
ak sa nou aktyèlman

1831
01:19:51,840 --> 01:19:54,380
jwenn isit la se n boutèy demi lit n, ki se gwo.

1832
01:19:54,380 --> 01:19:55,830
>> Gade nan ki jan pi bon se sa ki.

1833
01:19:55,830 --> 01:19:56,780
Tankou yon koub bèl.

1834
01:19:56,780 --> 01:19:58,130

1835
01:19:58,130 --> 01:20:00,120
Se konsa, anpil pi efikas.

1836
01:20:00,120 --> 01:20:03,510
Si ou janm kapab, sèvi ak rantre sòt.

1837
01:20:03,510 --> 01:20:04,810
Li pral delivre ou tan.

1838
01:20:04,810 --> 01:20:07,670
Lè sa a, ankò, jan nou te di, si
w ap desann nan rejyon pi ba sa a,

1839
01:20:07,670 --> 01:20:09,480
li pa fè ki
anpil nan yon diferans.

1840
01:20:09,480 --> 01:20:11,360
Ou jwenn moute a dè milye
ak dè milye de entrain,

1841
01:20:11,360 --> 01:20:13,318
ou definitivman vle yon
pi efikas algorithm.

1842
01:20:13,318 --> 01:20:14,730

1843
01:20:14,730 --> 01:20:19,400
Epi, ankò, tab bèl nou nan tout
kalite ke ou nèg te aprann jodi a.

1844
01:20:19,400 --> 01:20:21,157
>> Se konsa, mwen konnen li te gen yon jou dans.

1845
01:20:21,157 --> 01:20:23,490
Sa a se pa nesesèman ale
ede ou avèk pset ou yo.

1846
01:20:23,490 --> 01:20:28,250
Men, mwen jis vle fè yon dechajman
seksyon ki se pa sèlman sou psets.

1847
01:20:28,250 --> 01:20:31,240
Tout materyèl sa a se jis
jwèt pou midterms ou yo.

1848
01:20:31,240 --> 01:20:35,430
Epi tou si ou fè kontinye sou ak CS,
sa yo, se fondamantal vrèman enpòtan

1849
01:20:35,430 --> 01:20:37,870
ke ou ta bezwen konnen.

1850
01:20:37,870 --> 01:20:41,700
Se konsa, kèk jou pral gen yon
ti kras pi plis èd pset,

1851
01:20:41,700 --> 01:20:44,600
men gen kèk semèn yo pral
pi plis kontni aktyèl

1852
01:20:44,600 --> 01:20:46,600
ki pa ka sanble super
itil ou kounye a,

1853
01:20:46,600 --> 01:20:51,215
men mwen te pwomèt si ou kontinye
sou pral trè, trè itil.

1854
01:20:51,215 --> 01:20:52,560

1855
01:20:52,560 --> 01:20:54,250
>> Se konsa, sa a, se li pou seksyon.

1856
01:20:54,250 --> 01:20:55,250
Desann nan fil la.

1857
01:20:55,250 --> 01:20:56,570
Mwen te fè li nan yon minit.

1858
01:20:56,570 --> 01:20:58,262

1859
01:20:58,262 --> 01:20:58,970
Men, gen ou ale.

1860
01:20:58,970 --> 01:21:01,240
Apre sa, mwen pral gen beye oswa sirèt.

1861
01:21:01,240 --> 01:21:03,464
Èske gen moun alèji ak
anyen, nan chemen an?

1862
01:21:03,464 --> 01:21:05,307

1863
01:21:05,307 --> 01:21:05,890
Ze ak lèt.

1864
01:21:05,890 --> 01:21:08,120
Se konsa, beye se yon pa gen okenn?

1865
01:21:08,120 --> 01:21:09,400

1866
01:21:09,400 --> 01:21:10,160
OK.

1867
01:21:10,160 --> 01:21:10,770
Tout dwa.

1868
01:21:10,770 --> 01:21:12,120
Chokola pa gen okenn?

1869
01:21:12,120 --> 01:21:12,620
Starburst.

1870
01:21:12,620 --> 01:21:13,837

1871
01:21:13,837 --> 01:21:14,670
Starbursts yo se bon.

1872
01:21:14,670 --> 01:21:15,170
OK.

1873
01:21:15,170 --> 01:21:17,045
Nou ap ale nan gen
Starburst semèn pwochèn lè sa a.

1874
01:21:17,045 --> 01:21:18,240
Sa a ki sa mwen pral jwenn.

1875
01:21:18,240 --> 01:21:19,690
Ou nèg gen yon gwo semèn.

1876
01:21:19,690 --> 01:21:20,460
Li espèk ou yo.

1877
01:21:20,460 --> 01:21:22,130
>> Kite m 'konnen si ou gen nenpòt kesyon.

1878
01:21:22,130 --> 01:21:25,300
Pset de klas yo ta dwe
soti nan ou pa Jedi.

1879
01:21:25,300 --> 01:21:28,320
Si w gen nenpòt kesyon
sou ki jan mwen resevwa nòt yon bagay

1880
01:21:28,320 --> 01:21:32,250
oswa poukisa mwen resevwa nòt yon bagay wout la mwen
t ', tanpri voye yon imèl ba m', vin pale avè m '.

1881
01:21:32,250 --> 01:21:34,210
Mwen se yon ti kras sa a fou
semèn, men mwen te pwomèt

1882
01:21:34,210 --> 01:21:36,340
Mwen ap toujou reponn nan 24 èdtan.

1883
01:21:36,340 --> 01:21:38,240
Se konsa, gen yon semèn gwo, tout moun.

1884
01:21:38,240 --> 01:21:40,090
Bon chans sou pset ou yo.

1885
01:21:40,090 --> 01:21:41,248
