Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n)
{
    int check_sum = 0;
    for(int i = 0; i < n - 1;i++){
        check_sum ^= mem[i];
    }
    if(check_sum == mem[n-1]) return 1;
    else return 0;
}

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