youngi,

in my example:

nsewca

000014

000114

000211

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.
