Problem Statement

Write a C program to compute the cumulative XOR sum of all elements in an integer array.

Input Format

The first line contains N (size of array). The second line contains N space-separated integers.

Output Format

Print a single integer representing the XOR sum of all elements.

Constraints

1 <= N <= 1000, 0 <= Array Elements <= 100000

            scanf("%d", &arr[i]);
        }
        // Write your code here
