Thursday is code puzzler day here at DZone. 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!

Ray Casting Algorithm

A ray casting algorithm checks if a point is inside or outside a polygon.  It's called Ray Casting because the typical solution for such a problem is to to create a horizontal ray starting at the given point and checking if it intersects the side of the polygon. Check out the Wikipedia page for more details.
