You guys are geniuses! How do you do it?

I believe there is an error in the example portion of your intructions that lends to some confusion.

Current:
"Putting these results together fusc(10) = fusc(5) = fusc(2) + fusc(3) = 1 + 2 = 3"

Should be:
"Putting these results together fusc(10) = fusc(5) = fusc(2) + fusc(3) = 1 + fusc(1) + fusc(2) = 1 + 1 + 1 = 3"

Even more accurately:
"Putting these results together fusc(10) = fusc(5) = fusc(2) + fusc(3) = fusc(1) + fusc(1) + fusc(2) = 1 + 1 + fusc(1) = 1 + 1 + 1 = 3"

The example should show all the steps of recursion. Currently it appears that fusc(3) directly equals 2 when actually there's another step of recursion that further expands fusc(3) into 2 more functions. I think it's important to show this extra step for clarity.
