Checksum Validation

Code

#include <stdio.h>

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

    return 0;
}

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

    int result = validate_checksum(arr, n);
    printf("%d", result);

    return 0;
}
