Draw a capital K 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.

1. Lift the pen. Turn left and move forward 40 pixels to the middle of the left edge.
2. Put the pen down and draw up 40 pixels to the top-left corner.
3. Draw to (40, 80), then back to (20, 40).
4. Draw to (40, 0).
