Checksum Validation

Code

#include <stdio.h>

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