Multipli ai lui k, ultima cifra k.

Scrieti definitia completa a subprogramului care are 3 parametri(a = tablou, n = dimensiunea, k = numar natural < 9).
Subprogramul returneaza nr de elemente din tablou care sunt miltipli ai nr k si au ultima cifra k.
/***********************************************************
Exemplu:
n = 6;
a = (9, 273, 63, 83, 93, 123);
k = 3;
Subprogramul v-a returna valoarea 4.(273, 63, 93, 123)
