Computer Applications
If arrays M and M + N are as shown below, write a program in Java to find the array N.
M = {{-1, 0, 2}, M + N = {{-6, 9, 4},
{-3, -1, 6}, {4, 5, 0},
{4, 3, -1}} {1, -2, -3}}
Answer
public class KboatSubtractDDA
{
public static void main(String args[]) {
int arrM[][] = {
{-1, 0, 2},
{-3, -1, 6},
{4, 3, -1}
};
int arrSum[][] = {
{-6, 9, 4},
{4, 5, 0},
{1, -2, -3}
};
int arrN[][] = new int[3][3];
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
arrN[i][j] = arrSum[i][j] - arrM[i][j];
}
}
System.out.println("Array N:");
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
System.out.print(arrN[i][j]);
System.out.print(' ');
}
System.out.println();
}
}
