Change of Office Hours

I have a meeting today that I fear will run late so I am moving my 5-6pm office hours to 6-7pm for tonight only. (still 8th floor wean) Leigh Ann

Redownload Chess Stubs

There was a bug in the starter code for the chess assignment. You should redownload the stubs from FrontDesk and resubmit your code again (with the changed stubs). Thanks to the students who gave failure cases, and I apologize for the error. See the discussion board for more details.

Chess Server Login and Results

The chess assignment will be released at midnight tonight. To play on the server you will need to create a handle: http://www.link.cs.cmu.edu/211/sign-up.html. Passwords are stored in PLAIN TEXT on the chess server, so use a junk password. Once you start playing the bots, the games that count towards your score on the assignment will be displayed on on the results page: http://www.link.cs.cmu.edu/211/chess-results.html.

Midterm 2 regrade

The answer to the Always Never Sometimes question that asked about the depth of complete binary trees should be "Never". If you answered "Never" but had points taken off, please bring your exam to any TA.

Midterm 2 grades

The grades have now been released. The mean and median were 97.6 and 98, respectively. The min and max scores were 56 and 130 (out of 140 possible points), respectively. You can pick up your exam outside Dr. Scherlis' office daily before 3:30 pm.

Second Exam

The second 211 exam will be given in lecture Thursday, Nov 6. All material from the semester is fair game, but expect more material from content since the first exam. This includes basic material from Tuesday's lecture on sorting (sorry to the one person I told otherwise in recitation today). Remember, you are allowed 1 piece (front and back) of 8.5in x 11in paper with whatever you want on it.

Practice Exam 2

We have put up the second exam from last fall as a practice exam. It is called midterm2.pdf. Answers and the practice test for the first exam are in the same directory.
