Chapter 18 Recursion (Fibonacci and Factorial) #1 - 18.2 (Fibonacci numbers) Rewrite the fib method in Listing 18.2 using iterations. Hint: To compute fib(n) without recursion, you need to obtain fib(n - 2) and fib(n - 1) first. Let fo and f1 denote the two previous Fibonacci numbers. The current Fibonacci number would then be fo + f1. The algorithm can be described as follows: fo = 0; // For fib(0) f1 = 1; // For fib(1) for (int i = 1; i
