Stiva

#875

Să se scrie un program care gestionează o stivă de numere întregi. Inițial stiva este vidă. Programul va citi de la tastatură o listă de operații, care pot fi:

• push X – adaugă valoarea întreagă X pe stivă;
• pop – elimină elementul din vârful stivei;
• top – afișează elementul din vârful stivei.

Programul va realiza asupra stivei operațiile citite, în ordine. Afișările se fac pe ecran, câte o valoare pe linie.
