    385 - Mini Parser.

    Medium

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

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

    Example 1:

    Input: s = “324”

    Output: 324

    Explanation: You should return a NestedInteger object which contains a single integer 324.

    Example 2:

    Input: s = “[123,[456,[789]]]”

    Output: [123,[456,[789]]]

    Explanation: Return a NestedInteger object containing a nested list with 2 elements:

    1. An integer containing value 123.

    2. A nested list containing two elements:

      i. An integer containing value 456.

      ii. A nested list with one element:

      a. An integer containing value 789

    Constraints:

    • 1 <= s.length <= 5 * 104
    • s consists of digits, square brackets "[]", negative sign '-', and commas ','.
    • s is the serialization of valid NestedInteger.
    • All the values in the input are in the range [-106, 106].
