input: Write a python function to identify the list with the greatest length using a lambda expression.
  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)
