input: Write a python function to find missing numbers from a list within the range 1 to 100.
  assert missing_numbers([1, 2, 3, 4, 5]) == [6, 7, 8, 9, 10, ..., 100]
  assert missing_numbers([4, 5, 1, 9, 8, 5]) == [2, 3, 6, 7, 10, ..., 100]
  assert missing_numbers([99, 100]) == [1, 2, ..., 98]
output: def missing_numbers(lst):
      return [num for num in range(1, 101) if num not in lst]
