#4785
Se consideră şirul crescător 1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, ..., în care fiecare număr natural nenul i apare de 2i-1 ori. Elementele unei matrice A cu M linii şi N coloane au valori astfel încât, parcurgând matricea de sus în jos, pe linii, și de la stânga la dreapta pe fiecare linie, se obțin primii M x N termeni ai șirului precizat. O submatrice a lui A este definită de patru valori, l1, c1, l2, c2 şi este formată din elementele Ai,j cu proprietatea că l1 ≤ i ≤ l2 și c1 ≤ j ≤ c2. Determinaţi suma elementelor pentru fiecare dintre Q submatrice date ale lui A.

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 summat 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.
