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(-9, 5) == 14
  assert absolute_difference(0, 0) == 0
  assert absolute_difference(-1, -1) == 0
  assert absolute_difference(3, -7) == 10
output: def absolute_difference(A, B): 
      return abs(A - B)
