Thanks for the great feedback -- it occurred to me that people could simply hard-code the "right" answers into their function. However, if I am using this to assess a candidate, I plan to actually read the code that they write :) And if a person is using this to assess their own skills, I trust that they know that an answer like the one above hasn't taught them anything.
Your guess about why I chose something that involves a little bit of setup is right on target, too. Being able to follow the instructions in a readme and get a simple project like this set up is a key skill to have, too.
