I get AC from the second attempt, and
if you want to get AC allways check that input:
(*)*)
Output must be NO
And:
(*)
Output must be YES
I hope this is helps you!

The amendment: for the input (*) you must have output NO, because
there is no closing comments!!! All before that mystake is true.

what do you mean that?
why
(*)*) should be no??
and if the input is:
(*(**)
(**)*)
what's the correct output??

Sorry to say , the example you gave,
example: "(*)*)" should outpu YES;
because you consider the first ')' as some word in comment,so its use
is not to match ,so this sentence is right;

(*(**) is 'YES' Because the second '(*' are the word in comment.

(**)*) is 'NO' Because the last '*)' has no '(*' with it.
