MIPS

Here is a swap function involving MIPS (Millions of Instructions Per Second). This was not a whole lot of fun, but it fulfilled my abligation to working with a second level language.

Does it work? Well only I know that for sure. I will tell you that it compiles. If you have access to a MIPS Simulator compiler, that accepts this code, you can always spend the weekend computing the hex output!
