Mavzu: Dasturiy ta'minotni testlash usullari va yo'llarini tadqiq qilish

Fibonachchi ketma-ketligi sonlar qatoridir:

0, 1, 1, 2, 3, 5, 8, 13, 21, ....
Har bir keyingi raqam oldidagi ikkita sonni qo'shish orqali topiladi.
Kutilayotgan natija: 1 1 2 3 5 8 13 21 34


Amaliy qism


2 ta test muvaffaqiyatli bajarildi.
