// Write a function Validate that will validate the brackets balance.
// A bracket is considered to be any one of the following characters: (){}[].
// Two brackets are considered to be a matched pair if the an opening bracket (, [, {
// occurs to the left of a closing bracket ), ], } of the exact same type.
// There are three types of matched pairs of brackets: [], {}, and ().
// A matching pair of brackets is not balanced if the set of brackets it encloses are not matched.
// For example, {[(])} is not balanced because the contents in between { and } are not balanced.
// Function must return true if the brackets a balanced and false, if not.
