Solution: Minimum Remove to Make Valid Parentheses

Understand how to apply stack data structures to identify and remove the minimum number of unmatched parentheses in a string. Learn the step-by-step approach to ensuring valid parenthesization by tracking indices and using LIFO operations, improving your string manipulation skills.

Statement

Given a string, s, that may have matchedEach opening parenthesis, (, has a closing parenthesis, ), for it. and unmatchedThere is no corresponding closing parenthesis, ), for an opening parenthesis, (. parentheses, remove the minimum number of parentheses so that the resulting string represents a valid parenthesization. For example, the string “a(b)” represents a valid parenthesization while the string “a(b” doesn’t, since the opening parenthesis doesn’t have any corresponding closing parenthesis.

Constraints:

$1 \leq$ s.length $\leq 10^3$
