Midterm question 4

I got several complains in relation to material coverage of question 4. To clarify: parts A and C were briefly introduced in lecture 5 part B as far as I can recall. Part B were asking to using an iterator which was primarily the focus of lecture 5B. However, I will take your concerns into consideration and will make the whole question a bonus and distribute its marks on other questions in a way that is most favorite to your overall scores.
