input: Write a function to design a positive feedback loop for the given Python program that prints "hello" 10 times. The feedback loop should increment the loop counter `i` and print "You've got it!" when `i` reaches 10.
  assert positive_feedback_loop() == None
  assert positive_feedback_loop()->"hello"*10+"You've got it!"==None
output: def positive_feedback_loop():
      for i in range(10):
          print("hello")
      print("You've got it!")
