Question 836806
Note that the maximum x-coordinate the robot can reach is 9, and the maximum y-coordinate is 10. Try a few steps:


(1,1) --> (6,7) --> (2,7) --> (2,3) --> (7,9) --> (3,9) --> (3,5) --> (3,1) --> (8,7) --> (4,7) --> (4,3) --> (9,9) --> (5,9) --> (1,9) --> (1,5) --> (1,1)


We're back to where we started! The robot will visit 15 different points.
