Biror maqsadga erishish uchun eng asosiy kerak bo’ladigan narsalar:
1. Intention(niyat)
2. Discipline(intizom)
3. Consistency(doimiylik, uzluksizlik)

Majburiy emas, ammo juda katta yordam beradigani esa bu:
bir hamroh

Keling birgalikda 14 kunlik Data-Structure study-plan ni o’zimiz uchun challenge qilamiz va har kuni yechimlar bilan bo’lishamiz. Balkim video ko’rinishidagi yechimlar ham ta’minlanar. Birgalikda har kuni taxminan 2 3 ta masala yechish orqali Data Structure ga oid bilimlarimizni oshirib va yangilab olamiz. Ohirida esa badge ga ham ega bo’lamiz.

Qiziqishingiz mumkin yuqoridagi kodda sort ishlatilgan va nima uchun bu kod ning time complexity si NLogN emas deb, to’g’ri. Sortlash uchun NLogN. lekin bizdagi array ning hajmi 26 va bu array ni saralash uchun 26*log(26). Lekin, buni hisoblab ko’rsak 200 dan ham kam bu esa const time hisoblanadi. Unda nima uchun O(1) bo’lmadi deb o’ylayotgan bo’lsangiz tepadagi 2 ta so’zlarning uzunligi maximum 10ˆ5 ekanligi berilgan va biz ularni massiv shakliga keltirib to’liq yurib chiqdik bu esa O(N). Shunday qilib: O(N) + O(1) = O(N).
