Checksum Validation

#include <stdio.h>
#include <cstdint>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int data;
    data = 0;
    for(uint8_t i = 0; i < n-1; i++)
    {
        data = data^mem[i];
    }
    data &= 0xFFFF;
    if(data == mem[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;
}
