Question

Given an input string 'S', you are tasked with finding and returning all possible permutations of the input string.

The first and only line of input contains a string 'S' of alphabets in lower case characters.

Print all the permutations of the given string 'S' on separate lines.

Input: "abc"
Output: 
abc
acb
bac
bca
cab
cba

The input string may contain the same characters, so there can be duplicate permutations.
The order of permutations does not matter.
You do not need to print anything; it has already been taken care of. Implement the function to return the answer.

Accepted Answer

Return all possible permutations of a given input string.

Use recursion to generate all possible permutations of the input string.
Swap characters at different positions to generate different permutations.
Handle duplicate characters by skipping swapping if the characters are the same.
Return the list of permutations as an array of strings.
