input: Write a Python function to sort a list with 1 million integers using the Timsort algorithm.
  assert sorted_list([3, 2, 1]) == [1, 2, 3]
  assert sorted_list([10, 9, 8, 7, 6, 5, 4, 3, 2, 1]) == [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  assert sorted_list([5, 1, 4, 2, 8]) == [1, 2, 4, 5, 8]
output: def sorted_list(lst):
      return sorted(lst)
