Karel is practicing for the Robot Olympics. One of karel's events is the shuttle race. The shuttle race requires karel to move around two beepers in a figure 8 pattern. Write a program that instructs karel to walk a figure 8 pattern with as few instructions as possible. Karel must stop in the same place as it starts and must be facing the same direction.
