Given a square matrix, calculate the absolute difference between the sums of its diagonals.
For example, the square matrix is shown below:
1 2 3
4 5 6
9 8 9
The left-to-right diagonal = . The right to left diagonal = . Their absolute difference is .
Complete the function in the editor below. It must return an integer representing the absolute diagonal difference.
diagonalDifference takes the following parameter:
The first line contains a single integer, , the number of rows and columns in the matrix .
Each of the next lines describes a row, , and consists of space-separated integers .
Print the absolute difference between the sums of the matrix's two diagonals as a single integer.
11 2 4
4 5 6
10 8 -12
The primary diagonal is:
Sum across the primary diagonal: 11 + 5 - 12 = 4
The secondary diagonal is:
Sum across the secondary diagonal: 4 + 5 + 10 = 19
Difference: |4 - 19| = 15
Note: |x| is the absolute value of x
