Because that's not the input of the case your code is failing. Print something besides the input and check it.

I have the same problem. I see @Chrone79 has solved the isuue, but 'This comment has been hidden'. I even did a hack to return true for this case and then I got that is should return false... !?

In one Test It is showing '())' True even though it is False because of i coundn't submit my solution.Btw i passed all test except this one

Same thing happen to me Where In JavaScript I wrote the Function that passed 118 test failed 1 than after logging I found one Test is expecting
'())' string to be true even though it is false
