Matrix Operations

Professor Erind is having frequently matrix operations and he wants to develop a program for this purpose. He wants the program to read two matrices, then sum of the matrices to printed out.

Question:
Write a program that is going to read two matrices (A and B) then show the result of A + B. Note that the sum operation is the sum of every element of Matrix A with respective element of Matrix B.

Input specification
In the first line, you will be given the size of the two matrices: two integers m (the number of rows) and n (the number of columns) where 1 < m,n ≤ 100 and the elements of the matrices are less than 1000.

The following m rows contain n numbers for the first matrix. And then, the following m rows contain n integers for the second matrix.

Output specification
As the output, give m rows with n integers which is the sum of the two matrices

Sample Input I
  2 4
  1 3 5 2
  0 2 6 4
  8 9 3 7
  4 0 0 3


Sample Output I  
  9 12 8 9
  4 2 6 7

Sample Input II  
  3 4
  8 9 2 9
  9 6 5 1
  1 0 9 9
  9 1 7 0
  4 4 9 8
