As promised, I looked at the homework and have decided that we are not yet ready for the third section (“Trees and Merge”). So, that section has been cut from the homework (you will see it again next week, but that part is not due Thursday). To reiterate in bold:

YOU DON’T NEED TO DO SECTION 3 (“TREES AND MERGE”) ON HOMEWORK #2.

We’ll be set for that shortly, you can probably do it after Tuesday’s class, so if you want to work ahead, I will be including that in the next homework.

I have cut it out of the version of the homework I have put online, so you can, if you wish, acquire the revised version of homework 2.
