+matrix, calculate the absolute difference between the sums of its diagonals.
+
+For example, the square matrix arr is shown below:
+
+1 2 3
+4 5 6
+9 8 9  
+
+The left-to-right diagonal = 1+ 5 + 9 = 15.
+.The right to left diagonal =  3 +5 +9 = 17 . Their absolute difference is
+|15-17| = 2 .
+.
+
+Function description
+
+Complete the diagonal difference function in the editor below.
+
+diagonalDifference takes the following parameter:
+
+    int arr[n][m]: an array of integers
+
+Return
+
+    int: the absolute diagonal difference
+
+Input Format
+
+The first line contains a single integer, n, the number of rows and columns in the square matrix  arr .
+Each of the next n lines describes a row, arr[i] , and consists of n space-separated integers arr[i][j]
+
+.Constraints
+
+-100 <= a[i][j]  <= 100
+
+Output Format
+
+Return the absolute difference between the sums of the matrix's two diagonals as a single integer.
