Write me a code to modify array to maximize sum of adjacent differences and the other steps required given the following:
Modify array to maximize sum of adjacent differences | Returns maximum - difference - sum with array modifications allowed ..
Initialize dp [ ] [ ] with 0 values ..
for [ i + 1 ] [ 0 ] ( i . e . current modified value is 1 ) , choose maximum from dp [ i ] [ 0 ] + abs ( 1 - 1 ) = dp [ i ] [ 0 ] and dp [ i ] [ 1 ] + abs ( 1 - arr [ i ] ).
for [ i + 1 ] [ 1 ] ( i . e . current modified value is arr [ i + 1 ] ) , choose maximum from dp [ i ] [ 0 ] + abs ( arr [ i + 1 ] - 1 ) and dp [ i ] [ 1 ] + abs ( arr [ i + 1 ] - arr [ i ] ).

#Here is code to modify array to maximize sum of adjacent differences and the other steps required.
 def maximumDifferenceSum ( arr , N ) :
	dp = [ [ 0 , 0 ] for i in range ( N ) ]
	for i in range ( N ) :
		dp [ i ] [ 0 ] = dp [ i ] [ 1 ] = 0
	for i in range ( N - 1 ) :
		dp [ i + 1 ] [ 0 ] = max ( dp [ i ] [ 0 ] , dp [ i ] [ 1 ] + abs ( 1 - arr [ i ] ) )
		dp [ i + 1 ] [ 1 ] = max ( dp [ i ] [ 0 ] + abs ( arr [ i + 1 ] - 1 ) , dp [ i ] [ 1 ] + abs ( arr [ i + 1 ] - arr [ i ] ) )
	return max ( dp [ N - 1 ] [ 0 ] , dp [ N - 1 ] [ 1 ] )
if __name__ == ' _ _ main _ _ ' :
	arr = [ 3 , 2 , 1 , 4 , 5 ]
	N = len ( arr )
	print ( maximumDifferenceSum ( arr , N ) )
