I’ve got the algorithm fixed! It turns out the old version was too complicated. It was flipping which stack it moved pieces to when the count variable was an odd number, which was unnecessary. I’ve also moved the majority of the code into a package build target, so other people will be able to import it and use my structure and algorithm implementation. I’ve made the CLI tool more than just a test. Now I just need to write a README.md and add a few more tests, and I’ll be ready to ship!
