O'rta arifmetik

Ikkita butun son a va b berilgan. Ularning o'rta arifmetigini, ya'ni (a + b) / 2 ni toping. Natija kasr son bo'lishi mumkin.

func solve(a int, b int) float64 {
    // ...
}

Misollar

Input: a=10, b=20
Output: 15.0

Input: a=5, b=7
Output: 6.0

Input: a=100, b=50
Output: 75.0

Maslahatlar

1. orta = (a + b) / 2
2. Avval ikkala sonni qo'shing, keyin natijani 2 ga bo'ling — agar sonlar int bo'lsa, kasr natija uchun float64ga aylantirishni unutmang.
