code: def _Restructure(l, structure):
      """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]`.
