Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Would you happen to know some other cool katas with performance constraints ?

Great kata !
I had a really fun time searching for a solution that would make this damn random test pass and I found some great algorithms.
Beware of integer overflows :)
Same issue here, worked on my machine and failed for 450010, and thanks to you I changed :math.pow(n,3) |> round to nnn
I guess this is part of the difficulty : you have to know every nook and cranny of the language you use :)
