I predict you're going to get a lot fewer claps and responses, because those last ten questions are hard!

Indeed, I'm not sure how to do a bunch of them on first glance. I assume you're actually allowed to write a one-line functions (which takes two lines) because you need that for e.g. the Fibonacci numbers, but it's still not obvious.

I'll muse over these and if I get stuck, I'll whine at you. :-D
