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.
Ok, but in the description you are saying that: "Going to one direction and coming back the opposite direction is a needless effort". But if you travel in the shape of a box, and then return to where you started, you are doing a needless effort. I think the best plan in the case NWSE as in NSWE is to stay in the starting point. What do you think?
There is a test that doesn't make any sense. If you go North, West, South and finally East yo go back to the same initial point, and as the problem says the opposite directions neutralize each other. So Nort - South and West - East keeps you in the same point.
