Write a C program that calculates the sum of both diagonals in a square matrix. Implement a function that takes a square matrix and its size as input and returns the sum of the main diagonal and anti-diagonal elements.Input3 31 2 3 4 5 6 7 8 9OutputSum of the main diagonal elements: 15Sum of the anti-diagonal elements: 15

Given a 2D matrix of size NxN, print the sum of the elements of all its diagonals.Input FormatThe first line of input contains T - the number of test cases. The first line of each test case contains the N - the size of the matrix. Each of the next N lines contains N integers - the elements of the matrix.Output FormatFor each test case, print the sum of the elements of all the diagonals, separated by a new line. Refer to samples for more clarity.Constraints1 <= T <= 1001 <= N <= 100-100 <= ar[i][j] <= 100ExampleInput43-5 0 42 8 -63 7 11-425 -2-4 16-2 -3 -6 -5 50 38 7 10 -5 -3 306 3 70 9 -20 -7-9 9 -6 7 3 2-1 7 7 6 -4 38 5 6 -9 40 8Output4 -6 4 9 3-4-2 6 -43 80 -15 -29 22 86 51 13 4 4 8ExplanationTest Case 1Sum of the elements of the 1st diagonal: 4Sum of the elements of the 2nd diagonal: 0 + -6 = -6Sum of the elements of the 3rd diagonal: -5 + 8 + 1 = 4Sum of the elements of the 4th diagonal: 2 + 7 = 9Sum of the elements of the 5th diagonal: 3Test Case 2Sum of the elements of the 1st and only diagonal: -4Test Case 3Sum of the elements of the 1st diagonal: -2Sum of the elements of the 2nd diagonal: 5 + 1 = 6Sum of the elements of the 3rd diagonal: -4

For a given 2D square matrix of size N*N, the task is to find the sum of elements in the Principal and Secondary diagonals. For example, analyze the following 4 × 4 input matrix.a00 a01 a02 a03a10 a11 a12 a13a20 a21 a22 a23a30 a31 a32 a33Example:Input 1 :  6 7 3 4                   8 9 2 1                  1 2 9 6                 6 5 7 2Output 1 : Principal Diagonal: 26                     Secondary Diagonal: 14Intuition:1. The principal diagonal is constituted by the elements a00, a11, a22, a33, and the row-column condition for the principal diagonal is: row = column2. However, the secondary diagonal is constituted by the elements a03, a12, a21, a30, and the row-column condition for the Secondary diagonal is: row + column = N – 1
