#3575

N prieteni, numerotaţi de la 1 la N, beau bere fără alcool la o masă rotundă. Pentru fiecare prieten i se cunoaşte \( {C}_{i} \) – costul berii lui preferate. Din când în când, câte un prieten, fie el k, cumpără câte o bere pentru o secvenţă de prieteni aflaţi pe poziţii consecutive la masă, începand cu el, în sensul acelor de ceasornic. El este dispus să cheltuiască x bani şi doreşte să facă cinste la un număr maxim posibil de prieteni.

Se cere numărul de beri pe care le va cumpăra fiecare prieten k în limita sumei x de bani de care dispune. În caz că x este mai mare decât costul berilor pentru toţi prietenii de la masă, se vor achiziţiona maxim N beri.
