Given a string s containing just the characters (, ), {, }, [ and ], determine if the input string is valid.

An input string is valid if:

  1. Open brackets must be closed by the same type of brackets.
  2. Open brackets must be closed in the correct order.
  3. Every close bracket has a corresponding open bracket of the same type.

Constraints

  • 1 <= s.length <= 10^4
  • s consists of parentheses only '()[]{}'.
/**
* @returns {boolean}
*/
var isValid = function(s) {
};

module.exports = { isValid };
