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.

Thanks
you should be able to see solutions to 6 kyu at least. Are you sure you cannot?
You must solve/forfeit the kata to view solutions, and there's no way around that.
You can't, and there's already a pending suggestion for this feature.
You cannot reliably check for this either. In C, you have to hope that the caller did their work right.
No, there's no way in C to test whether a pointer is valid or not. The only thing you can reliably test for is
NULL.
