Terrain wrap function

Will, you will notice that my code is very similar to Sylvia's but I didn't copy and paste it! SHE wrote it and was nice enough to help me because I was getting really far behind. She sat down and explained it to me, and I typed it out myself. However the result is that my code is basically hers with different variable names. Hopefully that is ok? I totally understand what's going on in the code, and I can contact you during office hours to explain it if you want.
(Just trying to be open because I don't want to get in trouble for "cheating" and I REALLY don't want Sylvia to!)

Oh, and I called that "terrain wrap function" because I had some ideas for diamond.square.step that I wanted to run by you but now I have to be somewhere and will type it up later!

Thank you for telling me.

If you're struggling, consider having some office hours time with me. I happen to be around now (https://appear.in/usubioprogramming), but otherwise you're welcome to book some time for Tuesday.
