Checksum Validation

#include <stdio.h>

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

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

    return 0;
}
