I provided a code snippet below.
`
public static void main(String[] args) throws Exception {
int[][] matrix = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
System.out.println(hasSymmetry(matrix)); // returns true, so the isComputable condition is verified and the code not executed. Otherwise, it would return false.
}
public static boolean hasSymmetry(int[][] matrix){
// isComputable is defined somewhere else, and it works as expected.
if(!isComputable(matrix)){
return false;
}
int length = matrix.length;
// the loops are skipped without any error. I added the print statements for checking, but they simply don't happen.
for (int i = 0; i == length; i++){
System.out.println("Inside loop" + i);
for (int j = 0; j == length; j++){
if (matrix[i][j] != matrix[j][i]) {
System.out.println(matrix[i][j] + " vs " + matrix[j][i]);
return false;
}
}
}
return true;
}
}
`
Anyone has an idea why the loops are skipped?
- I tried making the conditions inside the loop to be i – 2 and j – 2, but it doesn’t work.
>Solution :
for (int i = 0; i == length; i++){
^^
...
for (int j = 0; j == length; j++){
^^
There is a mistake in the termination conditions of your for loops.
