There are two things I was very uncertain about with this task... First, the removeEldestEntry method in the LRUCache class doesn't actually appear to do what it is supposed to do, but we were not instructed to edit that class, so I didn't touch it. And the constructor for this class takes a capacity argument, however I have no idea what that value should be. I just picked 10 and hoped it would work. I don't know if either of those are related to why the task won't pass.
