One way to do it is count all the closing and opening parenthesis for each parenthesis and sum up the minimum of opening and closing parenthesis for a given parenthesis.

Edit- Ohk so this case is only valid if the opening comes before the closing one so its not a good solution. It can be done via dp maybe not sure

    It's gonna be fine, because string like "))((" is also Balanced Parenthesis

    It's just abount counting brackets
