input: Write a function to design a positive feedback loop for the given Python program that prints "hello" 10 times. If the loop completes, print "You've got it!".
  
  def positive_feedback_loop():
      for i in range(10):
          print("hello")
          i += 1
          if i == 10:
              print("You've got it!")
  
  assert positive_feedback_loop()=="hello"*10 + "\nYou've got it!"
  
output: def positive_feedback_loop():
      for i in range(10):
          print("hello")
      print("You've got it!")
