#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.
