All Things Fibonacci

It's everybody's favorite algorithmic sequence. Dig deep and you'll find bunny rabbits, golden ratios, and sunflower seeds. What's not to like? As a result, it shows up everywhere people write code. Here are my favorite Fibonacci-related problems on Cody. By the way, that image is of Leonardo of Pisa. History knows him as Fibonacci, but his friends never called him that. Maybe we should call these things "Leo sequences."
