I agree

I just realized that this is a very old kata, but oh well. Still.

Cool kata, but I don't really understand why the input and answer are stringified when it could just be an array of coefficients for both. Most of my answer was just handling the formatting, but isn't that really secondary to what the problem statement is asking from us?

Comparison of unsigned long to int. It wouldn't have mattered. But it's fixed.

C++ test code has compiler warnings.

My lack of paying attention and not fully reading the description caused me to write out my own DFA which I spent hours hammering out... on the other hand, that made me really brush up on subjects that I didn't give much thought to in school, so very good Kata indeed ^^

Thanks for adding this, I enjoyed it.

The difference between someone who knows how to use Python's standard library and someone who doesn't (e.g., me)

Nice

Basically a cleaner version of my solution, very nice!

facepalm
I just realized I left in the test case from writing in my local env... big oof

Thank you so much for asking this question @PatrickSile and for answering so clearly @agkg

Very nice, I still have a lot to learn about what is even possible in Python.
