Quite a difficult kata although it looks very easy at first.

Oh. Of course.

oh. the print

Woah. First time realizing you can 2D slice if you use np.

I'm learning a lot here in Codewars.

you could simplify it a bit (pun intended) by avoiding the != 0 in gray2bin

Oh I should have thought of this.
My inner math teacher is screaming.
Well played.

Merged! :)

А можно нормально условие задачи объяснить? при каких условиях и как должна быть показана камера? Вот реально влом каждый случай по отдельности разбирать и искать закономерности по ошибкам. В примере одно, в тестах другое, автор имел в виду третье. Там с точками, здесь без точек, тут скобки вплотную, здесь на расстоянии. Ну что за Х?

@dfhwze I personally think that you are doing a great job contributing and overall, so I didn't mean to be rude, sorry if that's what it sounded like. And I am sure that not too many people can do better than you. :)
I just consider that this particular kata is probably a little better suited for 6 kyu, but also not too far away from a 7 kyu rank.

Hi all, I'm going to go with the democratic approach for this and say 6 as it has more votes (per api call above). If someone needs me to change it to 6 let me know.

Maybe the admin can push it up to 6kyu then.
I would indeed prefer that the rank properly matched the perceived difficulty.

Thanks for stepping in and managing the discrepancy!
We'll see what the admin decides.
