That is the classic Fibonacci series: f(n) = f(n-1)+f(n-2); f(0)=f(1)=1. Google for
it and you'll find zillion solutions for it, either recursive or iterative or even in
closed form. Best of luck.

No, we don't hand out code in TSDN; we're very willing to help you to do your
own homework. Give it a try.
