input: Write a Python function to identify the list with the greatest number of elements using a lambda function.
  assert max_length_list([[0], [1, 3], [5, 7], [9, 11], [13, 15, 17]]) == (3, [13, 15, 17])
  assert max_length_list([[1, 2, 3, 4, 5], [1, 2, 3, 4], [1, 2, 3], [1, 2], [1]]) == (5, [1, 2, 3, 4, 5])
  assert max_length_list([[3, 4, 5], [6, 7, 8, 9], [10, 11, 12]]) == (4, [6, 7, 8, 9])
output: def max_length_list(lst):
      max_list = max(lst, key=lambda x: len(x))
      return (len(max_list), max_list)
