Gigel are un set de n cuburi. Fiecare cub este marcat cu un număr natural, de la 1 la n și i se cunoaște lungimea laturii – număr natural. Cu o parte dintre aceste cuburi Gigel va construi o stivă, astfel:
- fiecare cub se analizează o singură dată, în ordinea numerelor marcate;
- dacă stiva nu conține niciun cub, cubul curent devine baza stivei
- dacă cubul curent are latura mai mică sau egală cu cubul din vârful stive, se adaugă pe stivă;
- dacă cubul curent are latura mai mare decât cubul din vârful stivei, se vor înlătura de pe stivă cuburi (eventual toate) până când cubul curent are latura mai mică sau egală cu cubul din vârful stivei.
Să se afișeze numerele de pe cuburile existente la final în stivă, de la bază spre vârf.

Cum funcționează evaluarea?
www.pbinfo.ro permite evaluarea a două tipuri de probleme:
- probleme la care rezolvarea presupune scrierea unui program complet
- probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.
Problema Cuburi2 face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:
- Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
- Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.
Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
