A grasshopper is sitting on a little stone, which we'll call stone zero. Ahead of him, arranged in a line, are stones one, two, three, et cetera, all the way up to nine. The grasshopper would like to reach that ninth stone, for reasons unknown ... two: he could take one big jump, or two little ones. How many different paths can the grasshopper take to reach his destination?
