unsigned long long factorial(long num) { unsigned long long mult = 1; while (num > 1) { mult *= num; num--; } return mult; }

int main() { long n; cin >> n; for (long i = 0; i < n; i++) { long current; cin >> current;

    unsigned long long fact = factorial(current);
    long sum_of_digits = 0;
    while (fact > 0) {
        sum_of_digits += fact % 10;
        fact /= 10;
    }

    cout << sum_of_digits << endl;
}
return 0;

}

Can anyone explain what's wrong in my code? Only 2/4 test cases have successfully ran, and all remaining test cases were unsuccessful.

def factorial(num)
