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(-3, 5) == 8
  assert absolute_difference(0, 0) == 0
  assert absolute_difference(10, -2) == 12
  assert absolute_difference(-7, -3) == 4
output: def absolute_difference(A, B):
      return abs(A - B)
