#4787

Elevii celor două clase de a șaptea din școală merg în excursie. În fiecare clasă sunt câte N elevi. Ovidiu și Mihnea, fiind liderii celor două clase din care fac parte, doresc să analizeze reușita excursiei, în funcție de gradul de compatibilitate dintre elevii participanți la excursie. Pentru a determina acest grad, fiecărui elev din cele două clase îi este atribuit un coeficient de amabilitate.
1. Determinați gradul de compatibilitate dintre cele două clase.
2. Determinați, pentru fiecare elev din clasa lui Ovidiu, numărul de elevi din clasa lui Mihnea cu care acesta poate lega o prietenie durabilă.
