Hi @himanshukumarclassic37.hk,
listen in this question get all the permutations and before adding them to the arraylist just check that if the arraylist contains that permutation before then don’t add the permutation,if it does not have then add the permutation. and before printing just sort the arraylist.

To check if an Arraylist contains a specified element you can use the contains() method.
