Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int *ptr, i, result=0;

    ptr=mem;
    // skip the checksum byte
    for (i=0, ptr=mem; i < (n-1); i++, ptr++) { 
        result ^= *ptr; 
    }
    return ((result ^ *ptr) == 0 ? 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;
}
