This Java program calculates the Fibonacci sequence using an iterative approach. The Fibonacci sequence is a series of numbers in which each number (after the first ...

Explanation: The fibonacci(int n) method recursively calls itself to calculate the nth Fibonacci number.; The base case is when n is 0 or 1, in which case it returns n directly.; For n greater than 1, ...

That is, the Fibonacci number of some number n is the Fibonacci number of n-1 plus the Fibonacci number of n-2; thus making it a fun exercise in recursion, baby!
