# --description--
<p>确定生成的括号字符串是否平衡;也就是说，它是否完全由成对的开/关括号（按此顺序）组成，其中没有一个错误嵌套。 </p>例子： <p class='rosetta__paragraph'> （空）是的</p><p class='rosetta__paragraph'> <code>[]</code>是的</p><p class='rosetta__paragraph'> <code>][</code>假</p><p class='rosetta__paragraph'> <code>[][]</code>是的</p><p class='rosetta__paragraph'> <code>][][</code>假</p><p class='rosetta__paragraph'> <code>[]][[]</code> false </p><p class='rosetta__paragraph'> <code>[[[[]]]]</code>是的</p>
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.
**Examples:**
| Input | Output |
| ------------------------- | ------ |
| <code>\[]</code> | true |
| <code>]\[</code> | false |
| <code>[][]</code> | true |
| <code>]\[]</code> | false |
| <code>\[]]\[\[]</code> | false |
| <code>\[\[\[\[]]]]</code> | true |
