input: Write a function to print the absolute difference between two given numbers.
  
  def absolute_difference(A, B): 
      return abs(A - B) 
    
  # Driver Code 
  A = 9
  B = 5
  print(absolute_difference(A, B))
  
  # Test Cases
  assert absolute_difference(9, 5) == 4
  assert absolute_difference(-9, 5) == 14
  assert absolute_difference(0, 0) == 0
  assert absolute_difference(3.5, -3.5) == 7.0
output: def absolute_difference(A, B): 
      return abs(A - B)
