P1.8 Consider a robot that has been placed in a maze. The right-hand rule tells you how to escape from a maze: Always have the right hand next to a wall, and eventually you will find an exit. The robot can: Move forward by one unit. Turn left or right. Sense what is in front of it: a wall, an exit, or neither. Write an algorithm that lets the robot escape the maze. You may assume that there is an exit that is reachable by the right-hand rule. Your challenge is to deal with situations in which the path turns. The robot cant see turns. It can only see what is directly in front of it.
