Data Structures using C++

The Fibonacci sequence is the series of integers

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,

See the pattern? Each element in the series is the sum of the preceding two items. There is a recursive formula for calculating the n-th number of the sequence (the 0-th number if Fibonacci(0)=0):

Fibonacci(n) = n, if n = 0 or 1, and

Fibonacci(n) = Fibonacci(n-2) + Fibonacci(n-1), if n > 1

Write a recursive version of the C++ function Fibonacci.
