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
