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.
I just tried a few different solutions and all worked fine. Try again but before that verify your code (infinite loop or...).
Please which language? A request timeout is not the fault of the kata (so it is not an issue) but a problem - as it is said - of server load at CW. Post a bug if you want: https://www.codewars.com/topics/bug-reports or be patient and try later:-)
