Checksum Validation

Code

#include <stdio.h>
#include <stdint.h>
int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int t=0;
    for (int i=0;i<n-1;i++){
        t ^=*(mem+i);
    }
    mem=mem+(n-1);
    return (*mem==t)?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;
}
