input: Write a function to print the absolute difference between two given numbers.
  
  def absolute_difference(A, B): 
      return abs(A - B) 
  
  assert absolute_difference(9, 5) == 4
  assert absolute_difference(10, 5) == 5
  assert absolute_difference(3, 7) == 4
  assert absolute_difference(-5, 7) == 12
  assert absolute_difference(-5, -7) == 2
output: def absolute_difference(A, B): 
      return abs(A - B)
