This is definitely something where tastes vary, for example you can see below several people assumed you can multiply any numbers, and that actually worked because the numbers are co-prime, but strictly you need LCM (and since I had LCM in my toolkit I used it)

I try to write solutions which would work for inputs like mine but I'm not fussed if, for example, my code panics on hypothetical "valid" inputs that I didn't consider.

So e.g I have panics for nonsense input like, "Pipe networks with more than one Start can't be solved" and "Uneveen seed list cannot work as described in problem" [Yes that's a typo] but I also have "Should not send signals unexpectedly" and "Surely not all the stones have X velocity 0"
