Note: This document is formatted as a text file using the IBM character set. To view it correctly, you should save this file and read it using a DOS editor such as EDIT, or change the current fixed-width typeface to a monospaced linedraw font, such as "MS Linedraw". Apologies if you don't have an IBM compatible computer or a monospaced linedraw font. If you don't have a linedraw font and your computer can understand Truetype fonts (most can these days), click here to download the MS Linedraw font.
I could reformat this using ASCII art or even GIFs, but it would take a long time and not be so pretty. Also, this would be impractical for the solutions.
