Using only the commands driveDistance to move forwards, turnLeft(angle 90) to turn, and traceOn and traceOff, create a program that efficiently as possible has the Linkbot draw a 3x3 grid of red squares forward and to the right of its starting point, with each square having a side length of 6. The Linkbot should end back at its starting position, facing forward. (A setSpeed command is provided at the beginning to speed up the robot's drawing.)
