input: Write a function to design a positive feedback loop for the given python program. If the loop successfully completes 10 iterations, it should print "You've got it!". The function should take the original program as input and return the modified program as output.
  
  assert positive_feedback_loop("for i in range(10):\n    print(\"hello\")") == "for i in range(10):\n    print(\"hello\")\n    i += 1\n    if i == 10:\n        print(\"You've got it!\")"
  assert positive_feedback_loop("for i in range(5):\n    print(\"hi\")") == "for i in range(5):\n    print(\"hi\")\n    i += 1\n    if i == 5:\n        print(\"You've got it!\")"
  assert positive_feedback_loop("for i in range(3):\n    print(\"hey\")") == "for i in range(3):\n    print(\"hey\")\n    i += 1\n    if i == 3:\n        print(\"You've got it!\")"
