You don't need to read input or print anything. Permutation of a String in Python Using Different Methods The following turned out to be the best solution: It first checks the base case: if both start and end are equal to in.length(). In this video, we discuss the recursive approach to printing all subsequences . will it be O(nlogn) for time ? The following code in Java uses recursion to create all possible substrings from a string. xml 153 Questions, Wildcard pattern for RoutingAppender of Log4j2, http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html. http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html. There is a lot to be learned from Honza's answer.I suggest you try and rewrite that as a recursive algorithm.

Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? Where does the version of Hamapil that is different from the Gemara come from? As you can observe we get unique sub-sequences for every set-bit and thus no 2 combinations can be same as 2 numbers cannot have same binary representation. The process will continue with substrings(1,2), and (1,3), until (1,5) when the program will run substrings(2,2).
