parameters: (l, structure)
docstring: Returns the elements of list l structured according to the given structure.
  
    A structure is represented by a list whose elements are either
    `None` or a non-negative integer. `None` corresponds to a single
    element in the output list, and an integer N corresponds to a nested
    list of length N.
  
    The function returns a data structure whose shape is given by
    `structure`, and whose elements are taken from `l`. If `structure`
    is a singleton, the function returns the single data structure
    implied by the 0th element of `structure`. For example:
  
        _Restructure(["foo", "bar", "baz", "qux"], [None, 2, None])
          -> ["foo", ["bar", "baz"], "qux"]
  
        _Restructure(["foo"], [None]) -> "foo"
  
        _Restructure(["foo"], [1]) -> ["foo"]
  
        _Restructure([], [0]) -> []
  
    Args:
      l: A list.
      structure: A list whose elements are either `None` or a non-negative
        integer.
  
    Returns:
      The elements of `l`, restructured according to `structure`. If
      `structure` is a list of length 1, this function returns the
      single data structure implied by `structure[0]`.
docstring_summary: Returns the elements of list l structured according to the given structure.
docstring_tokens: Returns the elements of list l structured according to the given structure .
