input: Write a function named clean_me that takes a function definition as its input and modifies the function to eliminate any redundant lines. The function should return the modified function definition. If the input function has no redundancy, return the function unchanged.
  
  def clean_me(func):
      modified_func = func.replace("print("Hi, my name is "+name+".")", "print("Hi, my name is "+name+". I am special and nothing else matters.")")
      return modified_func
  
  assert clean_me("def just_me(name):\n    print("Hi, my name is "+name+".")\n    print("I am special and nothing else matters.")\n    print("What about you?")") == "def just_me(name):\n    print("Hi, my name is "+name+". I am special and nothing else matters.")\n    print("What about you?")"
  
  assert clean_me("def another_func(text):\n    return text.upper()") == "def another_func(text):\n    return text.upper()"
output: def clean_me(func):
