its not giving any output , please tell me what is the error
Recursion-Dictionary Order(Larger)
Can you explain your logic for this problem?
i have first of all made all the permutaions by recursion and saved all of them in the arraylist, and returned it . For taking considerations of the duplicate , i have taken one more function which will handle to not to have duplicates, at the end when the arraylist is returned , i have sort the items in the array list in lexico order and printed it
your permutation function is not working properly, check that.
Also, for removing duplicates, you can have a hashset instead of arraylist, it only contains non duplicates elements. And to sort the arraylist lexicographically, you can just do Arrays.sort or Collections.sort, it will do the same.
