#3903
Se dă o matrice A, formată din N linii și N coloane. Asupra unei submatrice cu colțul din stânga-sus aflat pe linia l1 și coloana c1, și colțul din dreapta-jos aflat pe linia l2 și coloana c2, se poate efectua operație de mărire a elementelor cu un număr întreg v. Afișați matricea A, după efectuarea a Q astfel de operații.

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 Diff2dArrays 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.
