// same code without illegal characters
import java.io.*;

public class GFG {
static void Sum_of_Diagonals(int[][] matrix, int N) {
int Pd = 0, Sd = 0;

for (int k = 0; k < N; k++) {
for (int l = 0; l < N; l++) {
if (k == l)
Pd += matrix[k][l];
if ((k + l) == (N - 1))
Sd += matrix[k][l];
}
}
System.out.println("Sum of Principal Diagonal:" +Pd);
System.out.println("Sum of Secondary Diagonal:" +Sd);
}
static public void main(String[] args) {
int[][] b = {
{ 8, 2,13, 4},
{ 9,16,17, 8},
{ 1,22, 3,14},
{15, 6,17, 8}
};
Sum_of_Diagonals(b, 4);
}
}
