Multimi3

#697

Se consideră două numere naturale impare p şi q şi A={1,2,3,4,5,. . .,p*q} mulţimea tuturor numerelor naturale cuprinse între 1 şi p*q.

Să se scrie un program care determină p mulţimi, notate A1, A2,…, Ap cu proprietăţile:

• Numărul de elemente ale fiecărei mulţimi Ai, 1 ≤ i ≤ p, este egal cu q;
• Ai ∩ Aj = ∅ , 1≤i<j≤p;
• A1 ∪ A2 ∪ ... ∪ Ap = A;
• Sumele elementelor fiecărei mulţimi Ai, 1≤i≤p, sunt egale.
