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, print "You've got it!" after printing "hello" for the 10th time. The function should take a number as input indicating the number of times to print "hello".
  assert positive_feedback_loop(10)=="""hello
  hello
  hello
  hello
  hello
  hello
  hello
  hello
  hello
  hello
  You've got it!"""
  assert positive_feedback_loop(5)=="""hello
  hello
  hello
  hello
  hello
  You've got it!"""
  assert positive_feedback_loop(0)==""
  assert positive_feedback_loop(1)=="""hello
  You've got it!"""
output: def positive_feedback_loop(n):
      result = ""
      for i in range(n):
          result += "hello\n"
      if n > 0:
          result += "You've got it!"
      return result
