One test case is not passing

#1


my one test case is not passing, find flaw in my code and how to correct it.

@shivamgoel150 your logic doesn’t seem to be correct. your code is only handling cases where simple braces like this ‘( )’ are used else it is giving wrong answer.
try to change your approach.
