Be aware that using a long string of letters (ex: abcdefghijklmnopqrstuvwxyz) will take a significant amount of time!
The same code for generating anagrams, written in several different languages to compare performance
Run the Ruby with ./anagrams.rb [letters] on unix/macos; ruby .\anagrams.rb [letters] for windows
Run the Python with ./anagrams.py [letters] on unix/macos; python .\anagrams.py [letters] for windows
Run the Rust by first compiling with rustc -C opt-level=3 anagrams.rs and then ./anagrams [letters] on unix/macos or .\anagrams [letters] for windows
The C version currently does not work
Make sure you have the respective runtime installed for whatever language you are trying to run; ex: install ruby to run the ruby version or python to run the python version. The website for each language will have instuctions on how to do this for your platform
