i m getting repeated answers. how can i remove them?

#2

store them in set. as it will only store the unique permutations.
use set < string > s;
Hit like if u get it

#3

the question says dont use set or map.

#4

use vector and sort them. If any permutation is equal to the previous one then don’t print it.
OR
you can sort the string initially and permutate accordingly
