A software that generates and displays all possible permutations of the provided strings through command-line is available.
This script is not only highly effective, but it is also incredibly efficient. The algorithm that this script utilizes is typically the same one used by Lisp programmers, so you can be sure to expect quality results from using it.
One minor drawback to keep in mind is that the Perl Cookbook does in fact offer an alternative permutation algorithm that is much faster and more flexible. However, if brevity is your top priority, then the current algorithm is definitely worth considering.
All in all, Permutations is a fantastic tool that should be in the arsenal of any serious software developer looking to facilitate efficient performance in their code.
