Question
Semin ew. code that finds the sum of two matrices. Use the following method header
public static int[][] addMatrix(int[][] a, int[][] b)
The rules for adding two matrices are:
1. both matrices should have the exact same dimensions (i.e. height and width) – you need to check for this rule in your program.
2. both matrices should have elements that have compatible types – you don’t have to add extra code to check this rule in your method as it will only accept int arrays.
