Problem: Valid Parentheses
Explore how to use a stack to validate parentheses strings consisting of (), {}, and []. Learn to implement a solution that checks for correct matching and nesting order by pushing opening brackets and verifying closing ones, enhancing your understanding of stack operations and their application in problem-solving.
We'll cover the following...
Statement
Given a string s consisting only of the characters '(', ')', '{', '}', '[', and ']', determine whether the string represents a valid sequence of brackets.
A string is considered valid if all of the following conditions are satisfied:
Every opening bracket is closed by a bracket of the same type.
Brackets are closed in the correct (properly nested) order.
Every closing bracket has a matching opening bracket of the same type.
Return True if the string is valid, and False otherwise.
Constraints:
