Write a function that accepts two square matrices (
N x N two dimensional arrays), and return the sum of the two. Both matrices being passed into the function will be of size
N x N (square), containing only integers.
How to sum two matrices:
Take each cell
[n][m] from the first matrix, and add it with the same
[n][m] cell from the second matrix. This will be cell
[n][m] of the solution matrix.
