input: Write a function to design a positive feedback loop for the given Python program that prints "hello" 10 times. If the loop completes (i.e., when `i` reaches 10), it should print "You've got it!" as a positive feedback.
  
  def add_feedback_loop():
      for i in range(10):
          print("hello")
          i += 1
          if i == 10:
              print("You've got it!")
  
  assert add_feedback_loop() is None
  assert "hello" in [call.o for call in mock_print.call_args_list]
  assert "You've got it!" in [call.o for call in mock_print.call_args_list]
output: def add_feedback_loop():
      for i in range(10):
          print("hello")
      print("You've got it!")
