Zona4

#1749

Considerăm o matrice pătratică cu N linii și N coloane. În această matrice sunt definite 4 zone:

• zona 1, formată din elementele situate strict deasupra diagonalei principale și strict deasupra diagonalei secundare;
• zona 2, formată din elementele situate strict deasupra diagonalei principale și strict sub diagonala secundară;
• zona 3, formată din elementele situate strict sub diagonala principală și strict sub diagonala secundară;
• zona 4, formată din elementele situate strict sub diagonala principală și strict deasupra diagonalei secundare;

Se dă o matrice pătratică și un număr natural Z, reprezentând o zonă din matrice. Să se determine suma elementelor din zona Z.
