Matrix search
Problem
Write a program that determines how many times an element equal to K occurs in a matrix.
Input
The first line contains the dimensions of the matrix separated by a space: the number of rows N and the number of columns M (\(1 <= N , M <= 100\)). The following N lines contain matrix rows, each – by M natural numbers separated by spaces. The last line contains an integer K.
Imprint
The program should output the number of matrix elements equal to K.
