Problem 3 is where Euler starts forcing us to consider resource limitations. Before, the most straightforward solution worked just fine, even if it used more resources than a less complex algorithm would.

Our first, and certainly not our last, encounter with the Fibonacci Sequence on Project Euler. Before we dive into Problem 2 together take some time to chew on it yourself if you haven’t already.

This is a lovely problem to start with. It has a straightforward brute-force loop solution as well as a nice analytic solution where you can calculate the solution directly without the need for much programming.
