Solution: Valid Parentheses

Explore how to validate if a string of parentheses is balanced using stack implementation in C#. Understand the step-by-step process to check for matching opening and closing parentheses, improving your problem-solving skills with a method frequently tested in coding interviews. This lesson helps you build confidence in handling stack-related challenges and analyzing algorithm complexity.

We'll cover the following...

Statement

Given a string, exp, which may consist of opening and closing parentheses. Your task is to check whether or not the string contains valid parenthesization.

The conditions to validate are as follows:

  1. Every opening parenthesis should be closed by the same kind of parenthesis. Therefore, {) and [(]) strings are invalid.

  2. Every opening parenthesis must be closed in the correct order. Therefore, )( and ()(() are invalid.
