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.

my problem here is if s = 0 and when you do s = s * 2 it should alwayse = 0? but what seems here that this is not the case?
and shouldn't you start from the right to left? because you're doing it from the left to right?
I think I'm missing something here, but you can view my solution to get a better idea of what I mean...
Ah, but it is! Can you elaborate on what doesn't look right about it? Maybe it looks "backwards"? I actually had to check it after your comment to make sure it worked correctly, but it does. I wrote a comment in response to @Lavios below to offer a theoretical justification for why it works. Maybe that will help, but if it doesn't, I'd be happy to answer any questions you have.
this doesn't look right?
