Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic her
    int dem=0;
    for(int i=0; i<n-1; i++)
    {
        dem ^= mem[i];
        if(i==n-2)
        {
        if(dem == mem[n-1]) return 1;
        else if(dem != mem[n-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;
}
