Mama vrea să acopere cu covoare o cameră cu lungimea de n metri și lățimea de m metri. Ea are la dispoziție oricâte covoare în formă de pătrat, de orice dimensiune, număr natural și respectă următoarele reguli:
- fiecare covor plasat are laturile paralele cu laturile camerei;
- covoarele așezate nu se suprapun;
- de fiecare dată se folosește cel mai mare covor care poate fi ales în acel moment;
- de fiecare dată covorul ales se plasează în așa fel încât zona neacoperită încă să fie un dreptunghi.
Știind dimensiunile camerei să se determine care este dimensiunea maximă a unui covor folosit și numărul total de covoare folosite.

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 Covorul 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.
