So I changed direction already

A co-worker told me recently that he was similarly decided to start doing practice exercises on codewars.com to expand his skills. 

I hadn't heard of the website, so I checked it out briefly.  I completed one kata in Java to see how it worked.  I liked that the site supports solutions to katas in multiple languages, which would help me with the goal of expanding my fluency.  I also liked that, at least for Java, unit tests are a part of the process, example tests are provided and that I could add my own tests to the suite.

So, I'm going to give this a shot and see what I can get out of it.  I'm also going to do a write up each exercise here to explain my solution and my thought process.
