I've got a terrible solution in progress for this challenge, and I cannot figure out how to make it ignore empty rows/columns to avoid reducing an empty list. I'm wondering two things: is there some cleaner way to get the indices between and including the first and last truthy values that doesn't involve r/, and is there some way I can actually get this to apply only to lines containing at least one truthy value?
S€T$ seems to give the right indices, but for some reason it's not actually stopping the link from being applied to the excluded indices
...¦ maps and then selects, doesn't it

and now that I have a working solution, I can't actually get a footer working that would let me run it on all test cases at once. Of course. codegolf.stackexchange.com/a/195732/85334

That's actually a really neat solution!
I can't see fast golfs, I'll think about it more though
