> Dastlab men bu proyektni dasturchi (software engineer) bo'lish uchun o'qish kerak bo'lgan mavzularning qisqacha ro'yxati sifatida yaratdim,
> ammo bu proyekt bugun siz ko'rib turgan katta ro'yxatga aylandi. Ushbu o'quv rejasidan o'tib, [men Amazon-ga dasturchi sifatida ishga yollandim](https://startupnextdoor.com/ive-been-acquired-by-amazon/?src=ciu)! 
> Ehtimol, menga o'xshab o'qishingizga to'g'ri kelmaydi. Baribir sizga kerak bo'lgan hamma narsa shu yerda.

## Bu nima uchun kerak?

Bu mening web dasturchi (web developer) darajasidan katta kompaniyada ishlaydigan dastur injineri (software engineer) darajasiga chiqish uchun qilgan ko'p oylik o'qish rejam.

![Coding at the whiteboard - from HBO's Silicon Valley](https://d3j2pkmjtin6ou.cloudfront.net/coding-at-the-whiteboard-silicon-valley.png)

Bu proyekt **yangi dasturchi injinerlar** uchun juda foydali. Va yana, oddiy programmistlikdan (masalan web yoki mobildan) dasturiy injinerlikka (dastur injinerlaridan computer science bilimlari talab qilinadi) o'tmoqchi bo'lganlar uchun foydali.


Agar sizda dasturchilik bo'yicha ko'p yillik tajribangiz bo'lsa, shuni bilingki: Google, Amazon, Facebook, va Microsoftga o'xshagan katta kompaniyalar dasturiy injinerlikni (software engineer) oddiy dasturchilik (software/web developer) dan farqli deb ko'radi va ular computer science bilimini talab qiladi.


Agar siz reliability engineer yoki operations engineer bo'lmoqchi bo'lsangiz, unda siz ixtiyoriy ro'yxatdan ko'proq o'qing (networking, xavfsizlik va boshqalar).

## Nima uchun foydali?

Ushbu loyihani boshlaganimda, men stack bilan heap-ni farqini bilmas edim,
Big-O ni nimaligini bilmas edim, tree-lar yoki graph-lar haqida hech qanday tushunchaga 
ega emas edim. Agar tartiblash algoritmini (sorting) yozishni so'rashganda, aniq qovun tushirgan 
bo'lar edim. Umrimda ishlatgan data strukturalarni hammasini tayyor holda ishlatganman 
(built-in library) va ularning asosida nimalar yotishini umuman bilmas edim. 
Juda ko'p kod yozgan bo'lsamda, lekin men hech qachon qandaydir data strukturani noldan yozmaganman.

Bu uzoq vaqt talab qiladigan jarayon bo’lib, sizga bir necha oy kerak bo'lishi mumkin. 
Agar siz allaqachon bu narsalarni ko'pini bilsangiz, bu resurslar sizni ko'p vaqtingizni olmaydi.

## Qanday foydalanish kerak?

Quyida foydalanish qoidalari berilgan bo'lib, bosqichlarni yuqoridan pastga tartibda bajarishingiz kerak.

Men natijalarni kuzatish uchun vazifalar ro'yxatini o'z ichiga olgan Github markup-idan foydalanmoqdaman.

**Bu kabi elementlarni tekshirishingiz uchun yangi "branch" yarating, so'ngra shunchaki qavs ichiga x qo'shib, ro'yxat elementlarini belgilashingiz mumkin: [x]**

     Branch-ni o'zingizga fork qiling va quyidagi buyruqlarni ketma-ketlikda bajaring:

Ulash uchun https://github.com/jwasham/coding-interview-university havola(link) ga o'ting va "Fork" tugmasini bosing  

    Shaxsiy(local) repo-ga ko'chirib oling

`git clone git@github.com:<your_github_username>/coding-interview-university.git`

`git checkout -b progress`

`git remote add jwasham https://github.com/jwasham/coding-interview-university`

`git fetch --all`

    O'zgarishlaringizni tugatganingizdan so'ng barcha qismlarni X bilan belgilang

`git add .`

`git commit -m "Marked x"`

`git rebase jwasham/main`

`git push --set-upstream origin progress`

`git push --force`

[Github-flavored markdown-haqida ko'proq ma'lumot](https://guides.github.com/features/mastering-markdown/#GitHub-flavored-markdown)


## O'zingizni omadsiz deb hisoblamang

- Omadli dasturchilar aqlli, ammo ularning ko'pchiliklari o'zlarini yetarlicha aqlli deb hisoblashmaydi.
- [Daho dasturchining afsonasi](https://www.youtube.com/watch?v=0SARbwvhupQ)
- [Yolg'iz qolish xavfli: Texnologiyada ko'rinmas monsterlarga qarshi kurash](https://www.youtube.com/watch?v=1i8ylq4j_EY)

## Video qo'llanmalar haqida


Ba'zi video darsliklarni faqat Coursera yoki EdX platformalari orqali ro'yxatdan o'tgan holda olish mumkin. 
Ular MOOC (ommaviy ochiq onlayn kurs) deb nomlanadi.
Ba'zan darslar sessiyada bo'lmaganligi sababli siz bir necha oy kutishingizga to'g'ri keladi.

    Bepul va har doim ham ochiq ommaviy manbalarni yaratishda o'z hissangizni qo'shishingizni xohlagan bo'lar edim. 
    Bu manbalar Youtube dagi video darsliklar ham bo'lishi mumkin. Masalan menga universitet 
    ma'ruzalaridan foydalanish yoqadi.

## Intervyu uchun bitta dasturlash tilini tanlang

Intervyuning kodlash qismini bajarish uchun o'zingizga qulay bo'lgan dasturlash tilidan foydalanishingiz mumkin,
lekin yirik kompaniyalar quyida berilgan tillarning biridan foydalanishni talab qilishlari mumkin:

- C++
- Java
- Python

Shuningdek quyidagilarni ham ishlatishingiz mumkin:

- JavaScript
- Ruby

Quyida intervyu uchun dasturlash tilini tanlash haqida yozgan maqolam: [Pick One Language for the Coding Interview](https://startupnextdoor.com/important-pick-one-language-for-the-coding-interview/).
 
Siz intervyu uchun tanlagan dasturlash tilida erkin kod yoza oladigan va o'z bilimingizga ega bo'lishingiz kerak.

**Yuqorida aytilganidek siz intervyu uchun bitta dasturlash tilini tanlashingiz kerak**

Mening tilga oid tavsiyalarim. Menda barcha tillar uchun resurslar yo'q shuning uchun sizda qo'shimcha ma'lumot bo'lsa tavsiya qilishingiz mumkin.
Agar siz bulardan birini o'qib chiqsangiz, masalalarni yechishda kerak bo'lgan barcha data strukturalar va algoritmlari bo'yicha bilimlarga ega bo'lishingiz kerak.
**Loyihadagi video resurslarni o'tkazib yuborishingiz mumkin**, agar ko'rib chiqishni xohlamasangiz.

[Tilga oid qo'shimcha resurslar.](programming-language-resources.md)

### C++

Men bularning ikkitasini o'qimaganman, lekin ular yuqori baholangan va Sedgewick tomonidan yozilgan. Sedgewick aka zo'rlar :)

## O'rganishni boshlashdan oldin

Mazkur ro'yxat bir necha oylar davomida shakllanganligi sababli biroz qo'ldan chiqdi.
Bu yerda men ba'zi yo'l qo'ygan xatoliklar bor, bu esa sizlarga yaxshiroq tajriba orttirishingizga yordam beradi.

### 1. Bularning barchasini eslab qolmaysiz

Men soatlab videolar ko'rardim va eslatmalar yozib qo'yar edim, va bir necha oydan so'ng hammasini eslab qola olmas edim.
Men yozib olgan eslatmalarim va fleshkartalarim yordamida takrorlab chiqishim uchun 3 kun sarfladim. 

Men qilgan xatolarni siz ham takrorlamasligingiz uchun iltimos o'qib chiqing:

[Retaining Computer Science Knowledge](https://startupnextdoor.com/retaining-computer-science-knowledge/).

Menga tavsiya qilingan kurs (shaxsan o'zim ko'rib chiqmaganman): [Learning how to Learn](https://www.coursera.org/learn/learning-how-to-learn).

### 2. Fleshkartalar(kartochkalar) ishlating

Muammoni yechish uchun, men fleshkartalar uchun sayt yaratdim, u yerga 2 turdagi fleshkartalar joylanadi: umumiy eslatmalar va kod. 
Har bir karta o'z formatiga ega.

Vebsaytdan telefon yoki tabletdan ham xohlagan joyda foydalana olishim uchun mobil telefonga moslangan sayt yaratdim.

O'zingizni saytingizni ham tekinga yarating:

- [Fleshkartalar sayti uchun repo](https://github.com/jwasham/computer-science-flash-cards)
- [Mening fleshkartalarim bazasi (eski versiya - 1200 ta kartalar)](https://github.com/jwasham/computer-science-flash-cards/blob/main/cards-jwasham.db):
- [Mening fleshkartalarim bazasi(yangi versiya - 1800 ta kartalar)](https://github.com/jwasham/computer-science-flash-cards/blob/main/cards-jwasham-extreme.db):

Yodingizda bo'lsin, menda assembly language va Python triviyalaridan tortib, machine learning va statistikani o'z ichiga olgan kartalarim bor. Bu esa talab qilinadigan narsalardan ham ko'p hisoblanadi. 
(Ya'ni bularning barchasini siz bir vaqtda o'zlashtirgan bo'lishingiz shart emas)

**Fleshkartalardagi eslatmalar :** Birinchi marta fleshkartadagi javobni topa olganingizda uni o'zlashtirilganlar qatoriga qo'shmang. Aksincha huddi shu kartani 
ajratib qo'ying va bir necha marta javob bering toki haqiqatdan ham javobni anglab yetguningizgacha.
Takrorlash natijasida ma'lumot miyangizga chuqurroq joylashadi.
 

Fleshkartalar uchun bir necha marta menga tavsiya qilingan alternativ vebsayt [Anki](http://ankisrs.net/). 
Bu sizning eslab qolishingizga yordam berish uchun takrorlash sistemasini ishlatadi. 
Buni ishlatish qulay va barcha platformalarda mavjud va cloud bilan sinxronizatsiya qilingan. iOS platformalari uchun narxi $25, lekin boshqa platformalar uchun tekin.

Anki formatidagi mening fleshkartalarim bazasi: https://ankiweb.net/shared/info/25173560 ([@xiewenya](https://github.com/xiewenya) ga tashakkur).

### 3. Ma'lumotlar tuzilmalari va algoritmlarini o'rganish jarayonida coding intervyu savollariga javob topishni boshlang.

O'rganayotgan narsalaringizni masalalar yechishda qo'llab ketishingiz kerak, 
aks holda o'rganganlaringizni tez unutishingiz mumkin.
Shaxsan menda shunday bo'lgan. Biror bir mavzuni masalan bog'langan ro'yxatlar (linked lists) ga oid mavzuni 
o'rganganingizdan keyin agar o'zingizni shu mavzuda erkin 
his qilishni boshlasangiz coding intervyu kitoblaridan linked list ga oid masala yechishga urinib ko'ring.
So'ng, keyingi mavzuga o'ting. Bir qancha vaqtdan keyin yana ortga qaytib linked listga yoki 
rekursiyaga oid masala yeching. Asosiysi o'rganish jarayonida ko'proq masalalarni yechishda davom eting.
Sizni ishga bilimingiz uchun emas, bilimingizni qo'llay olishingiz uchun qabul qilishadi.
Men sizlarga tavsiya qiladigan kitoblar va saytlar bor. 
Ko'proq ko'rish uchun havolaga o'ting: [Coding bo'yicha savollar ustida ishlash](#coding-boyicha-savollar-ustida-ishlash).

### 4. Takrorlang, takrorlang va yana takrorlang

Menda ASCII, OSI stack, Big-O notations va boshqa mavzularda eslatma varaqlarim bor. 
Ularni biroz bo'sh vaqtim bo'lganda o'rganaman.

Masalalar yechish jarayonida biroz tanaffus oling va o'zingizni fleshkartalaringizni takrorlab chiqing.

### 5. Diqqatingizni bir joyga jamlang

Atrofimizda juda ko'p narsalar bizni chalg'itib qo'yadi va qimmatli vaqtimizni oladi.
Shuning uchun diqqatni jamlash va konsentratsiya qilish oson emas. Buning bir usuli,
matnsiz biron musiqa tinglang, bu esa diqqatingizni jamlashingizga yordam beradi.

## Bu proyekt nimalarni o'z ichiga olmaydi

Bular keng tarqalgan texnologiyalar lekin bu proyekt ularni o'z ichiga olmaydi:

- SQL
- Javascript
- HTML, CSS, va boshqa front-end texnologiyalar

## Kunlik reja

Bazi mavzular bir kun oladi, va bazilariga bir necha kunlar kerak bo'ladi. Bazilari faqat o'rganish, kod yozish kerak emas.

Har kuni bitta mavzu olib, videolarini ko'rib, quyidagi tillarda kodda yozib chiqaman:
- C - struct-lardan va struct * oladigan funksiyalarni ishlatgan holda
- C++ - built-in tiplarni ishlatmagan holda
- C++ - built-in tiplarni ishlatgan holda, masalan STL-ning std::list
- Python - built-in tiplarni ishlatgan holda (Python-ni mashq qilish uchun)
- va testlar yozgan holda (oddiy assert() ishlatib)
- siz Java yoki boshqa tilda qilishingiz mumkin

Sizga bularni hammasi kerak emas. Intervyu uchun sizga [faqat bitta til](#intervyu-uchun-bitta-dasturlash-tilini-tanlang) kerak.

Nega turlicha yozish kerak?
- Mashq, mashq, mashq, ko'nglim ayniguncha. Shunda muammosiz tushimda ham qila olaman.
- Past darajada (low level) yoza olish uchun (masalan, garbage collection ishlatmagan holda)
- Har kunlik ishda built-in tiplardan bemalol foydalana olish uchun (production-da array listni yoki linked listni boshidan yozib o'tirmaymanku)

Har bir mavzuni tepadagi tarzda o'qiyolmasligim mumkin, lekin harakat qilaman.

Meni kodlarimni bu yerda ko'rishingiz mumkin:
 - [C](https://github.com/jwasham/practice-c)
 - [C++](https://github.com/jwasham/practice-cpp)
 - [Python](https://github.com/jwasham/practice-python)

Har bir algoritmni ikr-chikirini eslab qolishingiz shart emas.

Birinchi kodizni doskada yoki qog'ozda yozing, kompyuterda emas. Og'zaki test qiling. Keyin kompyuterda yozib test qiling.

## Oldindan nima bilish kerak

## Ma'lumotlar tuzilmasi (Data structures)

- ### Massivlar
    - Avtomatik ravishda o'lchamlarini o'zgartiradigan vektorni amalga oshirish.
    - [ ] Tavsif:
        - [Massivlar (video)](https://www.coursera.org/lecture/data-structures/arrays-OsBSF)

    - [ ] Vektorni bajaring (o'lchamini o'zgartiradigan massiv):
        - [ ] Massivlar va ko'rsatgichlar(pointerlar) yordamida kod yozishni mashq qiling va massivning indeksiga o'tish uchun indeks o'rniga pointer matematikasini ishlating.
        - [ ] Massivimiz elementlarini ushlab turadigan ichki (private) massiv
            - int massivni elementlarni saqlash uchun ishlatsak bo'ladi, faqat uning xususiyatlaridan foydalanmaslik kerak
            - 16 dan boshlang, agar boshlanayotgan son kattaroq bo'lsa 2 ning darajalarini ishlating(2 - 16, 32, 64, 128)
        - [ ] size() - massivdagi elementlar soni
        - [ ] capacity() - massiv o'z ichiga olishi mumkin bo'lgan elementlar soni
        - [ ] is_empty() - massiv bo'sh yoki yo'qligini tekshirish
        - [ ] at(index) - ko'rsatilgan indeksdagi massiv elementini qaytaradi. 
          Agar berilgan index massiv indekslaridan tashqarida bo'lsa xatolik qaytaradi.
        - [ ] push(item)
        - [ ] insert(index, item) - ko'rsatilgan indeksga elementni qo'shadi, indeksdagi eski element(lar)ni esa o'zidan o'ngga ko'chiradi 
        - [ ] prepend(item) - Massivning birinchi elementidan oldin yangi element qo'shish
        - [ ] pop() - Massivning oxirgi elementini o'chiradi va o'chirilgan elementni qaytaradi.
        - [ ] delete(index) - Massiv elementini index bo'yicha o'chiradi, Qolgan elementlar chapga ko'chiriladi
        - [ ] remove(item) - Berilgan qiymatni izlaydi va shu qiymatga ega index-larni barchasini o'chiradi
        - [ ] find(item) - Berilgan qiymatni izlaydi va shu qiymatga ega birinchi index-ni qaytaradi, agar topilmasa -1 qaytaradi
        - [ ] resize(new_capacity) // private function
            - Massiv hajmi to'lganda, uni ikki baravar oshirish uchun o'lchamini o'zgartiring
            - Massivda element olib tashlanganda, agar hajmi umumiy hajmning 1/4 ga teng bo'lsa, hajmini yarimiga o'zgartiring
    - [ ] Ish vaqt xarajati (Time)
        - O(1) Oxiriga qo'shish yoki olib tashlash (ko'proq joy ajratish uchun amortizatsiya qilingan), index, yoki o'zgartirish
        - O(n) boshqa joyga qo'shish yoki olib tashlash
    - [ ] Ish joy xarajati (Space)
        - elementlar xotirada yonma yon joylashgan, shuning uchun yaqinlik yordam beradi 
        - bo'sh joy kerak = (massiv hajmi >= n) * element hajmi, agar 2n bo'lsa ham O(n) hisoblanadi

    - [ ] [nega linked list-dan foydalanmaganingiz maqul (video)](https://www.youtube.com/watch?v=YQs6IC-vgmo)
    - [ ] Yodda tuting: siz "pointer to pointer" nimaligini tushuningiz kerak:
        (funksiyaga pointer berilganda, funksiya pointer ko'rsatib turgan adresni o'zgartirishi mumkin)
        Bu sahifa "pointer to pointer" ni tushinish uchun foydali. Lekin bunday list traversal stilini tavsiya etmayman chunki kodni o'qish va uni maintain qilish qiyin.
        - [Pointers to Pointers](https://www.eskimo.com/~scs/cclass/int/sx8.html)
    - [ ] Kodda yozaman (tail pointer va tail pointer-siz):
        - [ ] size() - listdagi elementlar sonini qaytaradi
        - [ ] empty() - agar list bo'sh bo'lsa true qaytaradi
        - [ ] value_at(index) - n-inchi elementning qiymatini qaytaradi (0 dan boshlab)
        - [ ] push_front(value) - listning boshiga element qo'shadi
        - [ ] pop_front() - birinchi elementni olib tashlab va uni qiymatini qaytaradi
        - [ ] push_back(value) - oxiriga element qo'shadi
        - [ ] pop_back() - oxirgi elementni olib tashlab va uni qiymatini qaytaradi
        - [ ] front() - birinchi elementni qiymatini qaytaradi
        - [ ] back() - oxirgi elementni qiymatini qaytaradi
        - [ ] insert(index, value) - index-ni joyiga value-ni joylashtiradi
        - [ ] erase(index) - index joyida turgan elementni o'chirib tashlaydi
        - [ ] value_n_from_end(n) - oxiridan sanaganda n-inchi elementni qiymatini qaytaradi
        - [ ] reverse() - listni teskari safga qo'yadi
        - [ ] remove_value(value) - value qiymatiga ega bo'lgan birinchi elementni o'chirib tashlaydi
    - [ ] Doubly-linked List
        - [Tavsif (video)](https://www.coursera.org/lecture/data-structures/doubly-linked-lists-jpGKD)
        - Kodda yozish shart emas

- ### Stack
    - [ ] [Stacks (video)](https://www.coursera.org/lecture/data-structures/stacks-UdKzQ)
    - [ ] Kodda yozmayman. Massivda stackni yaratish juda oson.

- ### Queue
    - [ ] [Queue (video)](https://www.coursera.org/lecture/data-structures/queues-EShpq)
    - [ ] [Circular buffer/FIFO](https://en.wikipedia.org/wiki/Circular_buffer)
    - [ ] linked-list dan foydalangan holda kodda yozaman (tail pointer bilan):
        - enqueue(value) - qiymatni queue-ni oxiriga qo'yadi
        - dequeue() - queue-ni boshidagi elementni o'chirib uni qiymatini qaytaradi
        - empty()
    - [ ] belgilangan o'lchamli massivdan foydalangan holda kodda yozaman:
        - enqueue(value) - mavjud xotirani oxiriga qiymatni qo'yadi
        - dequeue() - queue-ni boshidagi elementni o'chirib uni qiymatini qaytaradi
        - empty()
        - full()
    - [ ] Ish xarajati:
        - queue uchun linked-list ishlatib, list boshiga enqueue qilish va oxiridan dequeue qilish - bu yomon yondashuv. Chunki har safar dequeue qilinganda O(n) vaqt ketadi
        - enqueue: O(1) (amortized, linked list va massiv [probing])
        - dequeue: O(1) (linked list va massiv)
        - empty: O(1) (linked list va massiv)

        - adjacency map
    - Har bir usulni va ularni yaxshi & yomon tomonlarini o'rganib chiqing
    - BFS va DFS - bu algoritmlarini tezligini (time & space complexity), yaxshi & yomon tomonlarini, va ularni kodda yozishni biling

## Tizim Dizayni, Scalability, Ma'lumotlar bilan ishlash

**agar sizda 4+ yil ish tajribasi bo'lsa intervyularda sizga tizim dizayn bo'yicha savolar tushadi**
- Scalability va Tizim Dizayn juda katta mavzular hisoblanadi.
      Chunki katta ko'lamli traffikni ko'tara oladigan software/hardware-ni dizayn qilish uni ko'p qirralarini e'tiborga olishni talab qiladi
      Buni ustida bir talay vaqt o'tkazasiz
- Qirralar:
    - Scalability
        - Katta miqdordagi data to'plamlarni bitta qiymatga agregatlash
        - Bitta data to'plamini boshqasiga o'tkazish
        - Haddan tashqari katta miqdordagi data bilan ishlash
    - Tizim dizayni
        - funksional to'plami
        - interfeyslar
        - klaslar ierarxiyasi
        - ma'lum bir cheklovlar ostida tizimni dizayn qilish
        - soddaligi va mustaxkamligi

## Coding bo'yicha savollar ustida ishlash

Yuqoridagi barcha "computer science" mavzularini bilb oldingiz, endi coding bo'yicha masalalarga javob berishni mashq qilish vaqti keldi.

**Coding masalalarini yechishga tayyorlanish bu javoblarni yodlab qolish emas**

Masalalar yechishni mashq qilish nima uchun zarur:
- Muammoni aniqlash va kerakli ma'lumotlar tuzilmalari va algoritmlari mos keladigan joyni topa olish
- Masala uchun kerakli talablarni to'plash
- Huddi intervyudagi kabi muammoni yechish uchun qadam baqadam yurish
- Doskada yoki qog'ozda kod yozish, kompyuterda emas
- Yechimlaringizga ish joyi xarajati va ish vaqti xarajatini aniqlash
- Yechimlaringizni testlash

Suhbatda metodik, kommunikativ muammolarni hal qilish uchun ajoyib kirish qismi mavjud. 
Siz buni dasturlash uchun intervyu kitoblaridan ham topa olishingiz mumkin,
lekin men buni ular ichida juda foydali deb topdim:
[Algorithm design canvas](http://www.hiredintech.com/algorithm-design/)

Uyingizda doska yo'qmi? Bu tabiiy. Men o'zgacha insonman, menda kotta doskam bor. Doska o'rniga, rasm chizish uchun 
mo'ljallangan daftar ishlating. Shunda divanda o'tirib, mashq qilishingiz mumkin. Bu mening "divanga mo'ljallangan doskam".
Men rasmda qalamimni ham qo'shganman qulaylik uchun. Agar siz ruchkadan foydalansangiz, o'chirish istagi paydo bo'lishi mumkin. 
Tez Chalkashib ketadi. Shuning uchun men qalam va o'chirg'ichdan foydalanaman.

    - Qaytarish uchun va muammoni tanib olish uchun
    - Algoritm katalog qismi intervyularda tushadigan savollardan ancha qiyin
    - Bu kitob ikki qismdan iborat:
        - Data strukturalar va algoritmlar bo'yicha sinf darslik kitobi
            - Yaxshi taraflari:
                - Boshqa algoritm sinf darsliklari kabi qaytarish uchun yaxshi
                - Ishda va akademiyada bo'lgan o'zining masala yechish tajribasidan yaxshi hikoyalar bor
                - Kod namunalari C da
            - Yomon taraflari:
                - CLRS kabi zich va tushinishga qiyin bo'lishi mumkin, va hatto bir xil mavzularga CLRS yaxshiroq bo'lishi mumkin
                - Bazi narsalar yetarlicha yoritilmagani uchun, 7, 8, 9-boblar tushunishga qiyin (Ehtimol menikidan aqlliroq kalla kerakdir)
                - Meni noto'g'ri tushunmang: Menga Skiena, uni o'qitish uslubi, va mannerizmi yoqadi, lekin men Stony Brook universitetdagilar kabi emasman
        - Algoritm katalogi:
            - Bu kitobni sotib olishingizni asl sababi
            - Bu qismga yetib qoldim. Tugatganimdan so'ng bu yerni yangilab qo'yaman

    - Kitob 2004-yilda nashr etilgan va bir oz eskirgan, lekin kompyuterni qisqa vaqta tushunish uchun zo'r resurs
    - Muallif [HLA](https://en.wikipedia.org/wiki/High_Level_Assembly) ni kashf etgan. Shunday ekan, HLA haqida gaplar va namunalarga skeptik qarang. Keng ishlatilmaydi lekin assembly qanday ko'rinishini ko'rsatadigan namunalar
    - Bu boblar sizga kompyuterni tushunishda yaxshi bilim poydevori bo'ladi

    - Boshlang'ich bir ikki boblari muammolarga ajoyib yechimlar taqdim qiladi, lekin bu shunchaki kirish. 
      Bu kitob dasturning dizayn va arxitekturasi uchun qo'llanma

## Qo'shimcha o'rganish

    Men bularni har tomonlama rivojlangan dasturchi bo'lishingizga yordam berish va ba'zi texnologiyalar va algoritmlardan xabardor bo'lishingiz uchun qo'shdim,
    Natijada sizda kattaroq asboblar qutisi bo'ladi.

    - [CS 61B Lecture 39: Augmenting Data Structures](https://archive.org/details/ucberkeley_webcast_zksIj9O8_jc)

- ### Balanced search tree-lar
    - Kamida bitta balanced binary tree turini biling (va uni qanday yozishni ham biling)
    - "Balanced search tree-lar orasida, AVL va 2/3 tree-lar hozir o'tmishga aylangan, va red-black tree-lar ancha mashhurroq.
        Xususan qiziqarli bo'lgan o'z-o'zini tashkil qiladigan data struktura bu splay tree. Splay tree
        har safar key so'ralganda uni rotatsiyadan foydalangan holda root-ga o'tkazadi." - Skiena
    - Bulardan men splay tree-ni kodda yozishni tanladim. Bilishimcha intervyuda sizdan balanced search tree-ni
        yozishni so'rashmaydi. Lekin men baribir yozishni xohladim va tan olaylik splay tree-lar zo'r.
        Men juda ko'p red-black tree kodlarini ham o'qidim.
        - Splay tree: insert, search, delete funksiyalari
        Agar red-black tree-ni yozadigan bo'lsangiz faqat shularni yozishga harakat qiling:
        - Search va insertion funksiyalari, delete-ni tashlab ketavering
    - Men B-tree-lar haqida ko'proq o'rganmoqchiman chunki ular katta data to'plamlari bilan juda ko'p ishlatiladi
    - [Self-balancing binary search tree](https://en.wikipedia.org/wiki/Self-balancing_binary_search_tree)

    - **AVL tree-lar**
        - Amalda:
            Meni fikrimda AVL tree-lar amalda uncha ishlatilmaydi. Lekin men qayerda ishlatilishi mumkinligini ayta olaman:
            AVL bu search, insertion, va removal funksiyalarini O(log n) tezligida qila oladigan yana bitta struktura. AVL tree-lar
            red-black tree-larga nisbatan ancha uzil-kesil balanslangan. Shuning uchun insertion va removal sekin, lekin search tezroq.
            Shu sababli u bir marta qurilib qayta-qayta yuklanib ishlatiladigan data strukturalari uchun juda qo'l keladi.
            Masalan: til lug'atlari yoki dastur lu'gatlari (assembler va interpreter opcode-lari)

    - **Splay trees**
        - Amalda:
            Splay tree-lar asosan cache-lar, memory allocator-lar, router-lar, garbage collector-lar, data compressiya,
            rope data struktura, Windows NT, va hokazo componentlarni qurish uchun ishlatiladi

    - **Red/black tree-lar**
        - Bular 2-3 tree-ni tarjimasi (pastni ko'ring)
        - Amalda:
            Red-black tree-lar insertion, deletion va search uchun eng-yomon ish vaqtini kafolatlaydi.
            Uni shu xususiyati vaqt juda muhim bo'lgan dasturlarda foydali qiladi. Hamda eng-yomon vaqtni
            kafolat qiladigan data strukturalarni foydali bir qismi bo'lib ishlaydi;
            masalan, kompyutatsion geometriyada ishlatiladigan ko'p data strukturalar red-black tree-larga asoslanishi mumkin
            va hozirgi Linux kernellarda ishlatiladigan "Completely Fair Scheduler" red-black tree ishlatadi. Javaning 8 versiyasida,
            oldin bir xil bo'lgan elementlari saqlash uchun LinkedList ishlatgan HashMap data strukturasi o'zgartirilib 
            hozirda Red-Black tree ishlatadi

        - 2-3 tree-lar kamdan-kam ishlatiladi chunki uni kodda yozish uchun har xil node-lar kerak bo'ladi. O'rniga, odamlar Red Black tree-larni ishlatadi

    - **2-3-4 Tree-lar (shuningdek 2-4 tree nomi bilan tanilgan)**
        - Amalda:
            Har 2-4 tree uchun unga mos elementlari bir xil tartibda bo'lgan red-black bor. Insertion va deletion funksiyalari red-black
            tree-dagi color-flipping va rotation funksiyalariga tengma-tengdir. Bu xususiyati uni red-black tree-larni tagidagi mantiqni 
            tushunishda juda muhim rol o'ynaydi va shuning uchun ko'p kirish algoritm kitoblari red-black tree-dan oldin 2-4 treelar haqida gapiradi,
            garchi **2-4 tree-lar amalda uncha ko'p ishlatilmasada**.

        - Qiziq fakt: bu noma'lum, lekin B-tree-dagi B Boeing, Balanced, yoki Bayerdan (boshqa ixtirochisi) olingan bo'lishi mumkin
        - Amalda:
            B-Tree-lar ma'lumotlar bazasida keng ishlatiladi. Ko'p zamonaviy fayl tizimlari B-tree yoki uni boshqa variantlarini ishlatadi.
            Ma'lumotlar bazasidan tashqari, B-Tree-lar berilgan fayldagi tasodifiy bo'lakni tez o'qishga yordam beradi. Berilgan i fayl bo'lak adresini disk bo'lak adresiga aylantirish asosiy muammodir.
