cutting
Aveți o foaie de hârtie dreptunghiulară cu dimensiunile N x M centimetri. Foaia este împărțită într-o rețea de pătrate de 1 x 1 centimetri fiecare. Puteți considera foaia ca un sistem de coordonate – colțul din stânga jos este originea (0,0) a sistemului de coordonate și fiecărui vârf al unui pătrat îi sunt atribuite coordonate întregi – între 0 și N pe axa x și între 0 și M pe axa y. Primiți o succesiune de cereri de tăiere a foii de hârtie (sau mai exact, a părții care a mai rămas din ea). Fiecare cerere este definită de o pereche de numere întregi nenegative (p, q), reprezentând un punct din rețea, care este situat în porțiunea netăiată a hârtiei. Scrieți un program care după fiecare cerere calculează aria figurii rămase.

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 cutting 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.
