Показать описание
Join us in this video as we solve Leetcode Problem 20: Valid Parentheses. This problem challenges us to determine if a given string of parentheses is valid.

Problem Statement:
Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.

In this video, we'll walk through a solution with a time complexity of O(n) and space complexity of O(n). We'll discuss the approach of using a stack to keep track of the opening parentheses and popping them off when a closing parenthesis is encountered.

Follow along as we implement this efficient solution step by step, explaining the logic behind each decision. Learn how to handle edge cases and optimize your code for better performance.
