Not giving full points


#1

I submitted in less than 50 sec, but it is giving me only 180 points. Whenever I click on the submit button, it opens hint automatically.
Here is my code:
include <bits/stdc++.h>
int Solution::gcd(int A, int B) {
return __gcd(A,B);
}


#2

It may be because you are using library function


#3

instead of using bits/stdc++.h header try using just algorithm


#4

try using its basic form of code it would solve your problem
