Într-o școală sunt n
clase, fiecare având un număr diferit de elevi. Școală primește m
pachete cu cărți, fiecare cu un număr diferit de cărți. Pentru ca o clasa să primească un pachet, numărul elevilor din acea clasa trebuie să fie egal cu numărul cărților din pachet. Să se determine câte clase primesc un pachet de cărți.
