The Task is to find the absolute difference between the sums of the matrix's two diagonals as a single integer.

Solution

Explanation
Step 01: Take two variables named "diagonal1" and "diagonal2". Store initial value as zero(0).
Step 02: Iterate a for loop through the given array.
Step 03: While iterating the array we have to take the array matrix's row and column as index i to, then add the value to diagonal1.
Step 04: Reversing the second dimension of array to calculate secondary diagonal.
Step 05: Return absolute difference value.
