Wow, the binomial coefficients section was facinating! I thought Dr. Levin's presentation was fabulous as well, leading us on a story of three very different ways to think about the same abstraction (bit strings, lattice paths, and binomial coefficients).

I hope some of you found this to be as much of a joyful read as I did. In any event, following the agreed upon plan that Trostin proposed to us, our next task is to divide up the 13 exercises at the end of the section, and find pairs of volunteers willing to be responsible for presenting solutions to them when we meet for class next Tuesday.

Work as many of the 13 exercises at the end of section 1.2 as your 90 minutes allows. Exercises 8 and 13 do not have solutions, so leave these to last, but at least read them, so that when solutions are presented in class you are mentally ready to understand the solutions.

This assignment is due at 11:59 pm on Saturday, February 24th so that I have time on Sunday to evaluate your work.

During class today we will discuss the practice exercises from section 1.1 assigned last class. Anfal and Ved will share a detailed solution to exercises 4 and 10, and we will discuss any other exercise solutions that folks in class want to discuss.

Effort on the homework varied widely. Exemplary work was submitted by Parker, Cody, Johan, Turner, Akshay and Marin.

Read Section 1.2: Binomial Coefficients (pages 70 to 78 in our text), taking notes in your git repo.
