Given a string s represents the serialization of a nested list, implement a parser to deserialize it and return the deserialized NestedInteger.

\n\n

Each element is either an integer or a list whose elements may also be integers or other lists.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "324"\nOutput: 324\nExplanation: You should return a NestedInteger object which contains a single integer 324.\n
\n\n

Example 2:

\n\n
\nInput: s = "[123,[456,[789]]]"\nOutput: [123,[456,[789]]]\nExplanation: Return a NestedInteger object containing a nested list with 2 elements:\n1. An integer containing value 123.\n2. A nested list containing two elements:\n    i.  An integer containing value 456.\n    ii. A nested list with one element:\n         a. An integer containing value 789\n

给定一个字符串 s 表示一个整数嵌套列表，实现一个解析它的语法分析器并返回解析的结果 NestedInteger 。

\n\n

列表中的每个元素只可能是整数或整数嵌套列表

\n\n

 

\n\n

示例 1：

\n\n
\n输入：s = \"324\",\n输出：324\n解释：你应该返回一个 NestedInteger 对象，其中只包含整数值 324。\n
\n\n

示例 2：

\n\n
\n输入：s = \"[123,[456,[789]]]\",\n输出：[123,[456,[789]]]\n解释：返回一个 NestedInteger 对象包含一个有两个元素的嵌套列表：\n1. 一个 integer 包含值 123\n2. 一个包含两个元素的嵌套列表：\n    i.  一个 integer 包含值 456\n    ii. 一个包含一个元素的嵌套列表\n         a. 一个 integer 包含值 789\n
