I'll think about what can be done about the last-step hint for Spiral Matrix. I guess a reason why this tutorial format is not more widespread is that it's easy for the hints to be "off".
Aye, I don't know what the solution might be, and I know the language was already couched in terms of "probably you did something like this", so it wasn't completely prescriptive.
Maybe all it will take is another sentence that basically says "or maybe you are doing something else, and that's okay too"?
