Both in the lecture today ¡­

Both in the lecture today and the laboratory tomorrow, there will be a few additional slides on using Lisp, everything you need to know to complete the current problem set. As a general remark, one more time: we will be using a very restricted subset of Lisp in this class, and we aim to introduce all the necessary concepts, data types, and functions on the slides. Hence, in solving the problem sets, please review the slide copies as your primary reference.
