Draw a capital O with a black pen that is 2 pixels thick. The letter is 40 pixels wide and 80 pixels high.

The turtle starts at the center of the canvas, facing east. This is the bottom-left corner of the letter’s space.

1. Lift the pen and move to (20, 0), the bottom point of the letter.
2. Put the pen down and draw to (40, 20), then to (40, 60).
3. Draw to (20, 80), then to (0, 60), and (0, 20).
4. Draw back to (20, 0) to close the outline.
