After solving a problem, I always read alternative solutions and always find something new. Thanks man for such a cool idea

Man, I was happy that I solved the problem but this made me realize how ridiculously long all my code is lol

bumped to 100 (JavaScript)

muito pica,não sabia que números ímpares terminavam com 1

interesting

Forked and approved

cool!!!

I think that may be the intended lesson of the kata (locality of reference for row-major matrices which makes more efficient use of the cache)

Fixed

Love this solution! Using upto and downto in the context of a lift is just delightful.

A small improvement (arguably) could be to change stop to a proper bool throughout and then change

stop = 0
lift.reject!{|n| n == floor && (stop = 1)}

to

stop = lift.delete(floor)

The upper bound really should be in the description.

Uuuh, slick solution. I like it a lot.

Replaced with SVG (thanks to awesomead again)
