Given a string consisting of ()[]{}. Find the length of the longest Balanced Parenthesis in O(N)

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
Ohhk Thanx I didnt know the conditions.
Here is a similar problem
