Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    int result = *(mem + 0);
    int i;
    for(i = 1 ; i<n-1; i++)
    {
        result ^= *(mem+i); 
    }
    // Write your XOR scan logic here
    return result == *(mem+(n-1));
}

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;
}
