Write me a code to maximize sum of consecutive differences in a circular array and the other steps required given the following:
Maximize sum of consecutive differences in a circular array | Return the maximum Sum of difference between consecutive elements.
Sorting the array.
Subtracting a1 , a2 , a3 , ... . . , a ( n / 2 ) - 1 , an / 2 twice and adding a ( n / 2 ) + 1 , a ( n / 2 ) + 2 , a ( n / 2 ) + 3 , . ... . , an - 1 , an twice ..
Driver Program"
How can the above be solved in Python?

#Here is code to maximize sum of consecutive differences in a circular array and the other steps required.
 def maxSum ( arr , n ) :
	sum = 0
	arr . sort ( )
	for i in range ( 0 , int ( n / 2 ) ) :
		sum -= ( 2 * arr [ i ] )
		sum += ( 2 * arr [ n - i - 1 ] )
	return sum
arr = [ 4 , 2 , 1 , 8 ]
n = len ( arr )
print ( maxSum ( arr , n ) )
