in my example:
starting at top left as indicated by article
Line 1: instruction is not to move and pick up the can
Line 2: Move 1 square to west and pick up can (however you would hit the wall)
Line 3: Move an additional 2 squares to west and leave can (you would hit wall again)
I am unsure what the A score represents.
Somehow, I would have expected to be able to read the route the robot is going to take, based on prior leanings. Where am I going wrong?
Thanks a bunch.
