+
+## Description
+<section id='description'>
+Determine whether a generated string of brackets is balanced; that is, whether it consists entirely of pairs of opening/closing brackets (in that order), none of which mis-nest.
+<h4><strong>Examples:</strong></h4>
+
+| Input | Output |
+| --- | --- |
+| <code>[]</code> | true |
+| <code>][</code> | false |
+| <code>[][]</code> | true |
+| <code>][][</code> | false |
+| <code>[]][[]</code> | false |
+| <code>[[[[]]]]</code> | true |
