Checksum Validation

Code

#include <stdio.h>

// int validate_checksum(int *mem, int n) {
//     // Write your XOR scan logic here
//     return 0;
// }

int main() {
    int n, arr[100], sum=0;
    scanf("%d", &n);
    
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
        sum ^= arr[i];
    }
    // int result = validate_checksum(arr, n);
    printf("%d", !sum);
    
    return 0;
}
