Here’s the promised pre-reading for your exam. Two of the problem domains will be familiar to you, but the third is a template designed to illustrate a new type of exercise we’ll most likely be asking on the exam. Feel free to discuss the solution to the sample question we posed!

Here’s a sample solution to the problem given there (**corrected** 2017/12/08 to have the right work per node/level).** BUT**, try to solve it yourself first! The sample solution is really there mainly to make sure you understand how we intend to format the answer.

**NOTE** that we will expect you to be very familiar with the domains already given in our assignments (including assignment #6) are actively developing exciting new questions that explore those domains in different ways from what you’ve already seen.
