No Time for any more 9

I did the basic stuff for problem 9 and probably would have figured it out if I wanted to devote more time to it. I know. I know. Excuses. But I really am getting a bit bored with this chapter and I am over 2 weeks into it. I started question 10 and still have a lot to figure out. This chapter is on a short leash as I want to move forward with chapter 16 already. Remember, I have another entire Objective-C book to read when this one is done so maybe the challenging stuff will seep into my brain. Moreover, I think I will do all the Stanford exercises after I am done with the second book. It realistically looks like I won't be getting to any of the iOS books until late August or September... but I hope sooner.
