- * 20. Valid Parentheses
- *
- * Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.

- * 1. Open brackets must be closed by the same type of brackets.
- * 2. Open brackets must be closed in the correct order.
- *
- * Note that an empty string is also considered valid.
- *
- * Example 1:
- * Input: "()"
- * Output: true
- *
- * Example 2:
- * Input: "()[]{}"
- * Output: true
- *
- * Example 3:
- * Input: "(]"
- * Output: false
- *
- * Example 4:
- * Input: "([)]"
- * Output: false
- *
