Project Euler Problem 1
February 10, 2015
Project Euler is a collection of math problems intended for computer solution, and is one of the inspirations for Programming Praxis. The first problem on Project Euler, which also regularly appears on lists of phone interview questions, asks you to:
Find the sum of all the multiples of 3 or 5 below 1000.
Your task is to write a program that solves Problem 1 for arbitrary n; since the problem is simple, you must provide at least three fundamentally different solutions. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
