== As an exercise in Turtle Graphics. ==
As Quackery is not a well known language, here are my working notes in case anyone wants to take this approach. I think they're self-explanatory.
<pre>x,y| 0 1 2 3 4
---+---------------
0| 0 1 2 3 4
1| 15 16 17 18 5
2| 14 23 24 19 6
3| 13 22 21 20 7
4| 12 11 10 9 8
The turtle starts at (0,0) facing east.
When it walks a specified distance, it
leaves a trail of numbers behind it.
"right" means "turn right 90 degrees".
These are its movements to fill a 5*5 matrix.
4 walk right
4 walk right 4 walk right
3 walk right 3 walk right
2 walk right 2 walk right
1 walk right 1 walk right
1 walk
("1 walk": The turtle must vacate the final
position as it leaves numbers /behind/ it.)
