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