- // 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.
