It's Thursday, so it's time for another code puzzler. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable.

Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer.  It's all about the participation!

Find the Multiples 

This weeks task is to find all the sum of all multiples of 3 and 5 under 1,000. For example, the sum of multiples of 3 and 5 under 10 would be 23 (3 + 5 + 6 + 9).
