Maximum size subset with given sum | A Dynamic Programming solution for subset sum problem + maximal subset value . Returns size of maximum sized subset if there is a subset of set [ ] with sun equal to given sum . It returns - 1 if there is no subset with given sum ..
The value of subset [ i ] [ j ] will be true if there is a subset of set [ 0. . j - 1 ] with sum equal to i.
If sum is 0 , then answer is true.
If sum is not 0 and set is empty , then answer is false.
Fill the subset table in bottom up manner.

How can the above be solved in Python?
