Whew!

I changed try.cpp a bit. Instead of having one "good" word, I have one
"bad" word, which is "Bad." But really, when someone asks you, "How are
you?" odds are you're not going to have a negative response.

To get back into the swing of things, I'm following tutorials on
Google's dev education site. I had fun with the guessingame.

Honestly, I didn't know what I was doing with gcd. I know what the
program does, but I don't know how it does it. Something to do with
Euclidian algoritms.
