Solution: https://github.com/therajatg/DSA/blob/main/017-valid-parentheses.js
Valid Parentheses:
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.
Example 1:
Input: s = "()"
Output: true
Example 2:
Input: s = "()[]{}"
Output: true
Example 3:
Input: s = "(]"
Output: false
Example 4:
Input: s = "([])"
Output: true
Example 5:
Input: s = "([)]"
Output: false
Constraints:
s consists of parentheses only '()[]{}'.
