Today, I learn about: diarrhea diagnosis algorithm.

Algorithm ANALysis. Ha!

you said diarrhea

I hope you have a more complete version than that link has.

Seriously, that's pretty nasty.  Then again, I might actually prefer that to my 5-hour (with no breaks!) algorithms midterm.  If you want an idea of what'll be on it, have a gander at my last homework assignment.  In spite of all the pain it caused, this was the second easiest assignment we've had all semester; two questions didn't even have proofs.  I don't think the graders were wearing their glasses -- they gave me 55/55.

the version they gave us is more detailed, but it still looks like it is made from a printout in the early 80s.
