4 THE BUNNY EAR PROBLEM
We have bunnies standing in a line, numbered 1, 2, ... The odd bunnies (1, 3, ..) have
the normal 2 ears. The even bunnies (2, 4, ..) we'll say have 3 ears, because they
each have a raised foot. Recursively return the number of "ears" in the bunny line
1, 2, ... n (without loops or multiplication) for the number of bunnies entered by the
user.
bunnyEars2(0)→→O
bunnyEars2(1)→ 2
