O'rtadagi son

Uchta butun son berilgan. Ularni o'sish tartibida yozganda o'rtada turadigan sonni toping. Masalan, $4, 2, 6$ uchun javob $4$, $5, 5, 1$ uchun esa $5$.

Bitta qatorda uchta butun son $a$, $b$, $c$ ($|a|, |b|, |c| \le 10^9$).

Bitta butun son — o'rtadagi son.

Sonlar teng bo'lishi mumkin — shartlarda < emas, <= ishlating, aks holda $5, 5, 1$ kabi holatda hech bir shart bajarilmay qoladi.
