I understood the idea of this approach comparing to fullsearch by removing boolean() from the result. Your solution is wonderful!

depends on the language you solve this in ;)

Not done in Python, description says "and" instead of "plus".

Try refreshing your browser cuz I alr removed it in both test and basic test cases

should be working now

Here are coordinates which exist. Does this particular coordinate exist?
Doesn't matter if they're negative, that's not a special case. Testing for negative would be missing the point of the requirement - being outside the room.

Yes indeed, but it's not obvious and I personally think this should be stated in the description since negative indexes usually are correct data in Python.

@MrZizoScream - you should explain it better in the description

I'm having the same problem! It feels so close and so far. I also have a nested for-loop which I'm assuming is the problem, but I can't figure out what to replace it with.

XD
(asked a question at first then figured that out maself and dont know how to delete ma comment so heres a smiley)

did you finish? I passed 160 test cases failed 56. Can you explain the logic process you took.

It is a part of the kata that you have to find by yourself. The coding process is not always reversible.
