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 think it should be minimum 6 kyu, ideally 7.
it's not 5kyu. maybe 7, no less
If you cannot solve the kata and don't understand something it's unfortunate and can be upsetting for you but it is not a kata issue. You can refer to the documentation to try to debug your solution and maybe post more constructively: https://docs.codewars.com/training/troubleshooting

oh my god...
its 8kyu, not 7
