Write me a code to maximum weight transformation of a given string and the other steps required given the following:
Maximum weight transformation of a given string | Returns weight of the maximum weight transformation.
Base Case.
If this subproblem is already solved.
Don 't make pair, so  weight gained is 1.
If we can make pair.
If elements are dissimilar.
if elements are similar so for making a pair we toggle any of them . Since toggle cost is 1 so overall weight gain becomes 3.
save and return maximum of above cases.
Initializes lookup table and calls getMaxRec ( ).
Create and initialize lookup table.
Call recursive function.

#Here is code to maximum weight transformation of a given string and the other steps required.
 def getMaxRec ( string , i , n , lookup ) :
	if i >= n :
		return 0
	if lookup [ i ] != - 1 :
		return lookup [ i ]
	ans = 1 + getMaxRec ( string , i + 1 , n , lookup )
	if i + 1 < n :
		if string [ i ] != string [ i + 1 ] :
			ans = max ( 4 + getMaxRec ( string , i + 2 , n , lookup ) , ans )
		else :
			ans = max ( 3 + getMaxRec ( string , i + 2 , n , lookup ) , ans )
	lookup [ i ] = ans
	return ans
def getMaxWeight ( string ) :
	n = len ( string )
	lookup = [ - 1 ] * ( n )
	return getMaxRec ( string , 0 , len ( string ) , lookup )
if __name__ == " _ _ main _ _ " :
	string = " AAAAABB "
	print ( " Maximum ▁ weight ▁ of ▁ a ▁ transformation ▁ of " , string , " is " , getMaxWeight ( string ) )
