Se da o matrice mat cu m>=1 linii si n>=1 coloane, avand toate elementele distincte. Sa se interschimbe liniile pe care se afla cel mai mic si respectiv cel mai mare element din matrice.- de facut in CodeBlocks

2)Se da o matrice A cu m>=1 linii si n>=1 coloane. De asemenea, se dau q numere intregi. Pentru fiecare dintre acestea, sa se determine daca apare in matrice.- de facut in CodeBlocks

3)Se da o matrice cu m>=1 linii si n>=1 coloane. Sa se roteasca cu 90 de grade in sensul acelor de ceasornic matricea data.- de facut in CodeBlocks

4)Se da o matrice A cu m>=1 linii, n>=1 coloane. Se se permute circular coloanele matricei cu o pozitie la stanga.- de gandit
