Balanced parentheses

Question

Why does the last testcase fail ?

Answer 1

Snehil Pandey ,

your comment could be misunderstood.

')(a+b)('

this string contains the same nunber of opening and closing parenthesis, but it is not what is called *ballanced*.

this is ballanced: '()'

thus is not ballanced: ')('

Answer 2

Think of case like : )(a+b)(

Answer 3

Jayakrishna🇮🇳 is right
There should be same number of opening as well as closing parenthesis

Answer 4

This does not work either.

Answer 5

Your approach finding Number of '(' is equal to Number of ')' . But you should also consider the order.
See my example: )(a+b)(
It has 2 '(' and 2 ')' but those are not in proper way.. You need to rethink about your logic. Some changes needed..

Today only I discussed about same task and what is it how to do in another this thread. Have a look. You may get idea how to correct your code..
Hope it helps..
