Agar Node versiyasini boshqarish uchun [nvm](https://github.com/nvm-sh/nvm) dan foydalanayotgan bo'lsangiz, loyihaning ildiz papkasidan `nvm use` ni ishga tushiring va to'g'ri versiya tanlanadi. **O'yin maydoni (Playground)** `./src/playground/playground.js` faylida ma'lumotlar strukturalari va algoritmlar bilan o'ynashingiz, `./src/playground/test/playground.test.js` faylida esa ular uchun testlar yozishingiz mumkin. Shundan so'ng, playground kodingiz kutilgandek ishlashini tekshirish uchun quyidagi buyruqni ishga tushirishingiz kifoya: ``` npm test -- 'playground' ``` ## Foydali ma'lumotlar ### Manbalar - [▶ Data Structures and Algorithms on YouTube](https://www.youtube.com/playlist?list=PLLXdhg_r2hKA7DPDsunoDZ-Z769jWn4R8) - [✍🏻 Data Structure Sketches](https://okso.app/showcase/data-structures) ### Big O Notation _Big O notation_ algoritmlarni kirish hajmi oshgani sayin ularning ishlash vaqti yoki bo'sh joy talablari qanday o'sishiga qarab tasniflash uchun ishlatiladi.

Quyida eng ko'p qo'llaniladigan Big O notatsiyalarining ro'yxati va ularning kirish ma'lumotlarining turli o'lchamlariga nisbatan ishlashini taqqoslash keltirilgan. | Big O Notatsiya | Turi | 10 ta element uchun hisob-kitoblar | 100 ta element uchun hisob-kitoblar | 1000 ta element uchun hisob-kitoblar | | --------------- | ------------ | ---------------------------------- | ----------------------------------- | ------------------------------------ | | **O(1)** | O'zgarmas | 1 | 1 | 1 | | **O(log N)** | Logarifmik | 3 | 6 | 9 | | **O(N)** | Chiziqli | 10 | 100 | 1000 | | **O(N log N)** | n log(n) | 30 | 600 | 9000 | | **O(N^2)** | Kvadrat | 100 | 10000 | 1000000 | | **O(2^N)** | Eksponensial | 1024 | 1.26e+29 | 1.07e+301 | | **O(N!)** | Faktorial | 3628800 | 9.3e+157 | 4.02e+2567 | ### Ma'lumotlar tuzilmalarining operatsiyalari murakkabligi | Ma'lumotlar tuzilmalari | Kirish | Qidirish | Kiritish | O'chirish | Izohlar | | --------------------------- | :----: | :------: | :------: | :-------: | :--------------------------------------------------------- | | **Massiv** | 1 | n | n | n | | | **Stak** | n | n | 1 | 1 | | | **Navbat** | n | n | 1 | 1 | | | **Bog'langan ro'yhat** | n | n | 1 | n | | | **Hash jadval** | - | n | n | n | Mukammal xash funksiyasi bo'lsa, xarajatlar O (1) bo'ladi. | | **Ikkilik qidiruv daraxti** | n | n | n | n | Balanslangan daraxt narxida O(log(n)) bo'ladi. | | **B-daraxti** | log(n) | log(n) | log(n) | log(n) | | | **Qizil-qora daraxt** | log(n) | log(n) | log(n) | log(n) | | | **AVL Daraxt** | log(n) | log(n) | log(n) | log(n) | | | **Bloom filtri** | - | 1 | 1 | - | Qidiruv paytida noto'g'ri pozitivlar bo'lishi mumkin | ### Massivlarni saralash algoritmlarining murakkabligi | Nomi | Eng yaxshi | O'rta | Eng yomon | Xotira | Barqaror | Izohlar | | ------------------------- | :-----------: | :---------------------: | :-------------------------: | :----: | :------: | :--------------------------------------------------------------------------- | | **Pufakcha tartiblash** | n | n2 | n2 | 1 | Ha | | | **Kiritish tartibi** | n | n2 | n2 | 1 | Ha | | | **Tanlash tartibi** | n2 | n2 | n2 | 1 | Yo'q | | | **Heap tartibi** | n log(n) | n log(n) | n log(n) | 1 | Yo'q | | | **Birlashtirish tartibi** | n log(n) | n log(n) | n log(n) | n | Ha | | | **Tezkor saralash** | n log(n) | n log(n) | n2 | log(n) | Yo'q | Tezkor saralash odatda O(log(n)) stek maydoni bilan joyida amalga oshiriladi | | **Shell tartiblash** | n log(n) | depends on gap sequence | n (log(n))2 | 1 | Yo'q | | | **Sanash tartibi** | n + r | n + r | n + r | n + r | Ha | r - massivdagi eng katta raqam | | **Radiksli tartiblash** | n \* k | n \* k | n \* k | n + k | Ha | k - eng uzun kalitning uzunligi | ## Loyihani qo'llab-quvvatlovchilar > Siz ushbu loyihani ❤️️ [GitHub](https://github.com/sponsors/trekhleb) yoki ❤️️ [Patreon](https://www.patreon.com/trekhleb) orqali qo'llab-quvvatlashingiz mumkin.
