WebNov 2, 2012 · Instead of recursing on the letters of the word, you could recurse on the word length. For example, on the top level of recursion you could find all substrings with word.length() letters then word.length() - 1 letters and so on. This would probably require two recursive methods though, one to loop through the word lengths and one to loop … Web1. Start by adding an empty set to all possible subsets. 2.
