In an effort to not go a whole month without blogging, and in the interest of posting some code samples, I give you two solutions to Project Euler: Problem #1. If you’ve never heard of it, Project Euler (pronounced “oiler” after the Swiss mathematician Leonhard Paul Euler) is a set of increasingly difficult programming challenges. Participants can write their programs in any language and the only goal is to solve the problems and learn something. There are no prizes and you don’t have to show your work.

I had looked at this project years ago, and I swear I thought I had already solved some of them, but maybe I only thought about doing it. Anyway, I have two solutions to the first problem; one in Groovy and the other in Scala. Here, then, is how Project Euler describes the problem

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

So, the goal is to take a series of numbers from 0 to 1000, exclusive, find all the numbers divisible
