Checksum Validation

#include <stdio.h>

int validate_checksum(int *mem, int n) 
{
    int checksum_res = 0;
    for (size_t i = 0; i < n; ++i)
    {
        checksum_res ^= *(mem + i);
    }
    return !checksum_res;
}

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;
}
