Method 3: One by one fix characters and recursively generate all subsets starting from them. Your method is fine, but another recursive way and the way I would think about it is, since your substrings are single-consecutive pieces of the main string, you're dealing with two integer variables: a starting position and an ending position. So, the complexity of the above algorithm is where N is length of the input string. subs : a string that is used to store the currently generated subsequence. public class main { public static void main(String[] args) { generate("hello"); } public static void generate(String word) { if (word.length() == 1) { System.out.println(word); You want to use recursion and you have a working solution that uses recursion?
