Checksum Validation

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    unsigned int data = 0x0;
    for (int i = 0; i < (n - 1); i++) {
        data ^= mem[i];
    }

    return data == mem[n - 1] ? 1 : 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;
}
