This technical problem deals with how to print all possible permutations of a given string using recursion. For example, if the input string is "abc", the output would be all six possible permutations of the string: "abc", "acb", "bac", "bca", "cab", and "cba".
This is a good solution that uses recursion to generate all permutations of a given string. The time complexity of this solution is O(n!), which is optimal.
