-## Instructions
-
-Given a string 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.
