Program a robot to run a mile-long steeplechase where the steeples are made from beepers instead of wall segmesnts. the robot must jumb the steeples in this race by picking the beepers that make up the steeples. each steeple is made from beepers that are positioned in columns that are one, two or three blocks long. corners have either zero or one beeper. THere are no gaps in any of the steeples. Figure 5-7 shows on sample initial situation.
