i feel so sigma!

HA at least i came up with it too. i love eval for string operations.

...? Afaik, no.

Then let's improve test cases, so that other users won't have to go through this ordeal.

I have my ways to fall into every possible missing fixed test/trap... That doesn't help...

That can still refer to either those neighbours or the target room.

I'm sorry my kata's bore you. I'll try to do better next time.

I'd tend to think this is also an issue about missing fixed tests (problem was with roomGetter with s[0] kind of stuff).

oh... I see what the problem is...

just say "the suspicious room should have its occupant not always in sight". No need for a drawing, just an unambiguous sentence.

Seriously it became boring. I won't even search for it.

And I even got a timeout on one batch (I suspect it's the generatorbut maybe it's a server artifact, dunno)

I'm just going to draw a visualisation in the description of this 3th rule, to remove any ambigouty.

Oh, I see. That's right.

Yes, but one could sort numerical or string-based and you'd only find out on submit.
