you to rank them.

CS 223 - Data Structures
Many of you are considering taking CS 223, Data Structures, next semester.
The online syllabus and lecture notes are quite detailed. The textbook is
the The C
Programming Language by Kernighan and Richie. It is most influential
programming book ever written. It is the Bible. You can get it from Amazon
or free online from the Yale Library. There are also numerous Youtube videos starring Kernighan and others
discussing C and UNIX.
My advice is to write as many C programs as possible over winter break.
Also, I believe that Rob will be the course manager for CS 223.
Lecture: Running Time of Programs.

If your grade on the final exam is higher than your lower midterm grade,
it will replace that grade. The quality of mercy is not strained.
Farewell
As I stated at the start of class, we have covered lots of topics in this
course. I expect you to be able to show me what you know on the exam next Saturday. However, life happens. I expect that most of you will use
many of the concepts from this course in the coming years, particularly if you take
more computer science courses. Maybe not.
Cognitive psychology has shown that people learn better with intrinsic motivation than
with extrinsic goals. That is, you learn better if you want to learn than if
you just want to get a good grade or a good job. Therefore, my goal has been not merely for
you to learn computer science, but for you to love computer science.
Confucius advised: “Choose a job you love, and you will never have
to work a day in your life.”
Here is an illustrative example of the ephemeral nature of learning.
In some ways, this is the most important lesson from this class.
You must remember this.
