Tarmoqlanuvchi algoritmga doir misol yozish;

Butun son berilgan.Agar berilgan son musbat bo’lsa 1 ga oshiring, aks holda 2 ga kamaytiring.Hosil bo’lgan sonni ekranga chiqaruvchi programmani tuzilsin.

Takrorlanuvchi algoritmga doir misol yozish. n butun soni berilgan (n > 0).Quyidagi yig’indini hisoblovchi programma tuzilsin. S = n^2 + (n+1)^2 + (n+2)^2 + .. + (2*n)^2
