WebAug 19, 2013 · For getting subset elements, we can use following algorithm: After filling dp [n] [sum] by calling SubsetSum (A, n, sum), we recursively traverse it from dp [n] [sum]. For cell being traversed, we store path before reaching it and consider two possibilities for the element. 1) Element is included in current path.
