Thanks I solved it, can you let me know of the approach without using set ?

@dev_emma

You can use just recursion to do this.
Let’s say you have a function “printPermutation” which takes in an array and the start index and end index and prints all the permutation by swaping some OR none elements from start to end index.

Now keep each unique element at index 0 and then call the function for the rest of the array.

Print the array when you reach the end.
Let me know if you still need any help
