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.

Of course it doesn't!
I think it's all about input data, not a program itself.
From what I understand, no. If you go 5 times north then 5 times west, test passes but you're not at the starting point.

does this program guarantee that at the end of the program, the person will return back to the starting point ?
