I made this Kata because it was a simple idea that just hit me.

There aren't many low level C# Katas at least, so I wanted to try and help.

Looking at how all the other Katas are made, I tried to keep it as simple as possible but made sure to add a random test-case and everything too. It was a lot of fun to make.

After a few weeks, you'll end up asking how you could survive without them ;)
