the in-build factorial function of math includes that case

I don't understand how's this solution covers the '0!' case in which is suppose to be equal to 1.

okay , thank you !

There are no fancy optimizations required, but still the most trivial solutions might time out. Try to find a solution which does not loop all the way up to n.

Maybe the tests weren't strict at the time this solution passed them or they got lucky with the random tests. Sometimes the solutions aren't revalidated and some of them won't pass the tests anymore but they still show in Solutions tab.

i did same , but it showed timeout !

Thats nice but you need to train recursion HAHAHA

lol this guy

It is important to consider the case when i and n/i are both square root of n.

It's correct but it doesn't make you understand how to it works.

Marked as resolved.

Test with "a.b" doesn't pass.

Nope. It's still not resolved. You need to make a new reply and mark the checkbox below the comment box.

Thanks. I edited my previous comment and marked the issue as solved. Did that do it? I did not receive any feedback that it worked and the comment keeps marked as "Issue" in red.
