#1592

Eroul nostru, Costy merge la magazin pentru a-şi cumpăra biscuiţi. Vânzătorul îi spune că biscuţii costă S nasturi, şi că doreste ca plata lor să fie făcută cu n tipuri diferite de nasturi. De asemenea, vânzătorul precizează că ar dori ca numărul de nasturi din fiecare tip i să depăşească valoarea x[i], dar, să nu depăşească valoarea y[i]. Presupunând că baiatul are o infinitate de nasturi din fiecare tip şi că doreşte să rămână cu cât mai mulţi nasturi de tipurile n, n-1, n-2,.. în buzunar, ajutaţi-l să efectueze plata şi să pună cât mai repede mâna pe biscuiţi.
