Top Algorithm Interview Questions Explained - Valid Parentheses - Stacks, Easy
In these series I'm going to solve many Programming Interview questions related to algorithms and explain my thought process. I will try to be detailed and show you how a programmer thinks when confronted with such questions.
This one is about Stacks and is Easy:
Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.
An input string is valid if:
- Open brackets must be closed by the same type of brackets.
- Open brackets must be closed in the correct order.
- Every close bracket has a corresponding open bracket of the same type.
