Fibo_gcd

#3507

Se consideră Șirul lui Fibonacci cunoscut prin relația de recurență: \( {F}_{1} = 1 \); \( {F}_{2} = 1 \); \( {F}_{i} = {F}_{i – 2} + {F}_{i – 1}, i ≥ 3 \).

Pentru n perechi de numere x, y să se afișeze numărul de perechi pentru care numerele \( {F}_{x} \) și \( {F}_{y} \) sunt prime între ele.
