I want to write a function that does the following: Given a string 's' that contains only '(', ')', '{', '}', '[', ']', determine whether the string is valid. A valid string needs to satisfy:

• The opening parenthesis must be closed with the same type of closing parenthesis.
• Opening parentheses must be closed in the correct order.
• Each closing parenthesis has a corresponding opening parenthesis of the same type.
