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 was also wondering why is this 5 kyu. I don't know about C++ but in Python it's trivial :)
Anyway, I like this kata :)
It is not the author who gives the ranking but a moderator + there are lots of languages in this kata and they are not all with the same problems and difficulty. Moreover maybe you are among the best:-)
