Valid Parentheses | Stack | Leetcode 20

In this video, we solve the problem "Valid Parentheses." We determine if the input string of parentheses is valid by ensuring each opening parenthesis has a corresponding closing one in the correct order. Time Complexity: O(n), as each character is processed once. Space Complexity: O(n), due to the use of a stack to track unmatched parentheses.
