**Matrix Subtraction**  

A matrix of size 3x3 is subtracted from another of a similar size. Find the integers $A$, $B$, $C$, $D$, $E$, $F$, $G$, $H$, $I$ in the resultant matrix. 

	[1  2  3 ]        [4  5  6 ]      [A  B  C]
	[2  3  4 ]   -    [7  8  9 ]   =  [D  E  F] 
	[1  1  1 ]        [4  5  0 ]      [G  H  I]
 
 
In the text box below, enter each of the 9 integers, $A$, $B$, $C$, ... $I$ on a new line.

Cod sursa

public class Solution {
    public static void main(String[] args) {
        int[][] M = {{1, 2, 3}, {2, 3, 4}, {1, 1, 1}};
        int[][] N = {{4, 5, 6}, {7, 8, 9}, {4, 5, 0}};
                
        for (int i = 0; i < M.length; i++) {
          for (int j = 0; j < M[i].length; j++) {
            System.out.println(M[i][j] - N[i][j]);
          }
        }
    }
