I'd say removing less than nothing shouldn't remove everything, like this does for `removeminmax({1, 2, 3}, -1)`.

Yes, that's a nice bug. But anyway, it just piggybacks on Python's repurposing of negative indexes being mod len to being full-fledged elements of an ordered ring (so we can have from-till slicing). How does taking -3 items from the front seem? It should probably put three items there.:-P Anyway, it's easily fixed, just add >0 to the condition.

If you add extra values, make sure to identify the pattern so you add the correct ones :-) Nah, yeah, I agree it should just use >0. It's odd that the task explicitly allows negatives, but then doesn't test any. Is that usual here? Haven't been active here for a while, just sometimes think of it and return to solve a problem or two.

It's obvious you haven't been here for a long time. The tests are still abysmal. :-)

Is Set a Subset of Superset?
