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