Okay but still it's an bad kata as the attemps don't show any empty string to try. So how would you know what is wrong.

Thanks!

Thanks!

First it didn't even work with reset. After some time I checked again, then it worked.

I gave up and paste the solution from solution, still show STDERR. what to do?

i am getting STDERR: every time with different approach. Can anyone help?

not using ==/=== blew my mind. didn't get it at first. very clever.

I missed the point of imaging the dead cells. Thank you so much for taking time to explain it. Means a lot. Now I understood the problem properly.

yes, I didn't understand and that's why I requested to explain.
your answer could be, 'you won't'. thanks anyway

can anyone explain this please, For instance, the answer of [ [ 1, 0, 0 ], [ 0, 1, 1 ], [ 1, 1, 0 ] ] this one would be [ [ 0, 1, 0 ], [ 0, 0, 1 ], [ 1, 1, 1 ] ]. this is for the first generation. second generation answer would be [[0,0,0],[1,0,1], [0,1,1]]. if null row is deleted then remains [[1,0,1], [0,1,1]]
But the answer shows [[1,0,1], [0,1,1], [0,1,0]] the last 0,1,0 > where does it come from?

can you please explain the part of removing null row/collumn, still getting the same size?
