Array Matrix of Dimension [Java Programming]

The function calculateMatrixSum(int matrix[][], int m, int n) accepts a two-dimensional array matrix of dimensions m × n as input and returns the sum of odd elements whose row and column indices are the same. The function compiles successfully but fails to return the correct result for some test cases.

The code below has been commented out. Uncomment the code and debug it.
