Ukuthenga ngaphakathi nohlelo

Mayelana nalolu hlelo lokusebenza

Izinkinga zokubhala amakhodi ze-DSA kahle ngaphandle kokubhala umugqa owodwa wekhodi bese uba uchwepheshe ku-System Design.

I-Yeetcode iguqula imibuzo yengxoxo yakudala ibe yimibuzo ehehayo enezinketho eziningi, ikusize ufunde amaphethini futhi wakhe umuzwa wezingxoxo zobuchwepheshe kwa-Google, Amazon, Meta, Apple, nakwezinye izinkampani zobuchwepheshe eziphezulu.

KUNGANI I-YEETCODE?

Umkhuba wendabuko we-DSA udinga ukuhlala kukhompyutha ene-IDE. I-Yeetcode ikuvumela ukuthi ufunde noma kuphi—esitimeleni, ngesikhathi sasemini, noma ngenkathi ulinde emgqeni. Funda amaphethini afanayo okuxazulula izinkinga asetshenziswa onjiniyela asebethole imisebenzi ezinkampanini ze-FAANG.

Ngokungafani nezinye izinhlelo zokusebenza zengxoxo yokubhala amakhodi, i-Yeetcode isebenzisa ifomethi yemibuzo eyakha ukuqonda kwangempela ngaphandle kokukhungatheka kwamaphutha e-syntax noma ukulungisa amaphutha. Uzoba nekhono emiqondweni eyinhloko ngemuva kwe-algorithm ngayinye kanye nesakhiwo sedatha.

LOKHO OKUTHOLAYO:

→ Amakhulu ezinkinga ze-DSA ezikhethiwe ezihlanganisa i-Blind 75, i-NeetCode 150, kanye ne-Grind 75

→ Ukuhlukaniswa kwesinyathelo ngesinyathelo: Indlela → i-Algorithm → Ubunzima → Isixazululo
→ Izilimi zokuhlela eziyi-14 ezisekelwayo

→ Ukulandelela inqubekela phambili okuvumelanisa kuwo wonke amadivayisi akho

Izinkinga ezikhethiwe nsuku zonke ukwakha ukuvumelana

OKUPHELELE KU:

→ Onjiniyela besofthiwe abalungiselela izingxoxo zokubhala amakhodi
→ Abafundi be-CS abafunda izakhiwo zedatha kanye nama-algorithms

→ Ochwepheshe abamatasa abadinga enye indlela ye-DSA yeselula

Abashintshi bemisebenzi abaqondisa izindima zobuchwepheshe ezinkampanini ze-FAANG

→ Noma ubani olungiselela izingxoxo zobuchwepheshe ezinkampanini ezintsha noma e-Big Tech

INDLELA ESEBENZA NGAYO:

Inkinga ngayinye ikuhambisa ngezinyathelo ezine:

1. INDLELA - Qonda isu lokuxazulula izinkinga ngaphambi kokungena
2. I-ALGORITHM - Funda indlela yesisombululo efanele isinyathelo ngesinyathelo
3. UBUNZIMA - Ukuhlaziywa kwesikhathi nendawo kwe-Big O
4. IMIPHUMELA - Buyekeza ikhambi eliphelele ngencazelo eningiliziwe

Lolu hlaka lukufundisa ukucabanga njengonjiniyela omkhulu, hhayi nje ukukhumbula izixazululo.

IZIHLOKO EZIGCWALIWE:

Ama-Arrays & Hashing, Ama-Pointer Amabili, Ifasitela Elishelelayo, I-Stack, Usesho Lwe-Binary, Uhlu Oluxhunyiwe, Izihlahla, Ama-Tries, Umugqa We-Heap/Priority, Ukubuyela Emuva, Amagrafu, Ukuhlela Okuguquguqukayo, Ama-Algorithms Anobugovu, Izikhawu, Izibalo kanye neJiyomethri, Ukuphathwa Kwe-Bit

YAKHELWA I-MOBILE:

Yeka ukulinda uze ube nesikhathi sokuhlala kukhompyutha. I-Yeetcode yakhelwe kusukela phansi kuya phezulu efonini yakho:

→ Isixhumi esibonakalayo esihlanzekile esilungiselelwe izikrini ezincane
→ Amaseshini amafushane njengemizuzu emi-5-10
→ Qhubeka lapho ugcine khona kunoma iyiphi idivayisi
→ Landelela ngqo lokho okufundile

Kungakhathaliseki ukuthi ulwela umsebenzi wakho wokuqala wezobuchwepheshe noma ufinyelela ezingeni eliphezulu, i-Yeetcode ikunikeza umkhuba okudingayo—noma kuphi, nganoma yisiphi isikhathi.

Yeka ukucindezeleka nge-DSA. Zijwayeze ngokuhlakanipha nge-Yeetcode.

Yini entsha

- Light mode toolbar colors — "Yeetcode" title and streak pill number now visible in light mode
- Streak chip dark mode — uses --ion-color-dark which properly inverts in both themes
- System design card title — reduced so long titles don't fill the screen
- Android app name in dialogs — Google Sign-In dialog will
now say "Yeetcode"
