Hey I have a question, forgive me if this sounds silly I'm very much a beginner to this. But if I generate the full closure of S, won't the code just keep running forever because it's an infinite set? Or is there something specific I'm supposed to do that I'm just not understanding yet?

I think I just lost the ability to read. Permanently.

OMG, thank you so much for this. I kept seeing this syntax in katas and had no idea what was going on. Appreciate it so much!

How did I not know that you can multiply strings!? What on earth?

My brain isn't working... what even?
