A random walk is just what it sounds like. It's a math concept but still is pretty cool. You move randomly. One dimensional random walk is pretty boring. Two dimensional random walk is awesome, especially when you figure out the secret code. Looking inside for secret code is cheating. Guessing is fair, but there's a more proven way to do it. Hint: Second letter is i. You may comment the secret code to help other people out. Once you have the first four hints the secret code should be pretty easy to figure out!
Everything by me!
