long long age = 10;
Salida esperada:
long long expected = 5;Entrada:
long age = 10;

long long age = 70;

Cómo abordarlo
Inténtalo primero por tu cuenta y luego abre las pistas una a una.
Pista 1
The price depends on which age band the visitor falls into.
Pista 2
Check the youngest and oldest special cases before the middle ranges.
Pista 3
Pay attention to the exact endpoints so ages 3, 13, and 65 get the correct prices.
