Excellent work on the Homework 6 contest! Congratulations to all the prize winners.

Please fill out your Digital Measures course evaluation for Data Structures. Only 125 / 258 students (48%) have been submitted. If we get to 80% I will release the solutions to the final exam practice problems early (on Saturday morning).

A large collection of practice problems from old final exams have been posted on the calendar. The solutions will be posted a Sunday evening.

The Data Structures Final Exam will be on Tuesday May 13th from 3-6pm. Room assignments for the final:

      DCC 308 - Lab sections 1, 2, 3, 4, 5, 7, & 8

      DCC 324 - Lab sections 6, 9, & 10

Note there are typos in the room assignments on the RPI exam schedule .pdf (they will be fixed soon).

Check the exam schedule for your other courses. If you have a conflict according to RPI's official final exam conflict rules, contact the instructor by email before 5pm on Wednesday May 7th.

94/258 students (35%) have submitted their course evaluations through Digital Measures. Your feedback is very important. Please submit your comments to help us improve the course for future terms.

HW7 grades are now available on the homework submission server.
HW7 avg:42/50, std dev:8.4 approximate grades: 45&up=A, 40&up=B, 35&up=C, 30&up=D.

The tests have been graded and will be handed back in lab Wednesday. Please thank your TAs for their super-human efforts during a 17 hour grading session split over Monday and Tuesday.

Stats for the exam: Max=85, Average=57.1, StdDev=13.2. Approximate grades: 68&up=A, 56&up=B, 45&up=C, 40&up=D. Your semester average will be computed from the curved number score, not the approximate letter grade. These are approximate boundaries and, thus, there is still very little difference between a 67 and an 68 (so don't ask for a questionable regrade for 1 point).

The test solutions posted on the calendar by Thursday morning. No re-grade requests will be accepted until the solutions are posted. All re-grade requests must be submitted in writing to your graduate TA or the instructor within 7 days. Your entire test will be examined and your score may go up or down.
 

Max's office hours today are cancelled (due to anticipated lack of demand -- and since we are grading exams).

4 students were found in violation of the academic integrity policy on HW2. The instructor has met with the students, course grade penalties have been applied, and the incidents have been reported to the Dean of Students.

A beta test release of Dr. Memory for Mac OSX (has been tested on Lion 10.7.5 and Mavericks 10.9.1) is now available. See new instructions on the Memory Debugging page.

HW4 is about using the STL list container class and necessarily, using iterators to access the elements of a list (we can't use subscript with a list, only with vectors). The beginning of Lecture 9 (Tuesday) includes more discussion on iterators and usage of the erase & insert with the STL list class. You are encouraged to read through the material 9.1-9.6 as you start HW4. The notes for Lecture 9 are posted on the calendar. The material covered in 9.7-9.14 are not needed for HW4.

Because the snow day impacted HW3, we have given everyone 1 extra late day to use for the semester. Everyone now has a total of 4 late days instead of 3 late days to use as you need them. If you didn't finish debugging your memory leaks, writing your own test cases, or your order notation, you are encouraged to use the extra late day this week. However, you still may only use a total of 2 late days for HW3. We will start grading on Sunday morning.

HW4 has been posted on the calendar. It is due Thursday Feb 27th @ 11:59pm.

Today's office hours after 4pm are officially cancelled to allow our TAs and mentors who live off-campus to safely get home.

Because of all the snow... You will be allowed to complete checkpoints from labs 3 and 4 at the start of lab 5 or in your graduate lab TA's office hours next week.

The tests have been graded and will be handed back in lab Wednesday after you finish the 3rd checkpoint. Please thank your TAs for their hard work grading Monday evening & all day Tuesday (17 hours total!).

Stats for the exam: Max=99, Average=73.5, Standard Deviation=17.7. Approximate grades: 87&up=A, 73&up=B, 60&up=C, 50&up=D. Your semester average will be computed from the curved number score, not the approximate letter grade. These are approximate boundaries and, thus, there is still very little difference between a 86 and a 87 (so don't ask for a questionable regrade for 1 point).

See the test solutions posted on the calendar. All re-grade requests must be submitted within 7 days with a written explanation of the grading discrepancy. Your entire test will be examined and your score may go up or down.

Lab checkpoints must be finished before the end of your assigned lab section (ending 10 minutes before the hour). Because many students were dealing with course registration issues, lengthy compiler/editor installation, submission account problems, snow delays, etc., we will allow (for the first lab only!) students to get checked off for any remaining Lab 1 checkpoints at the beginning of next week's Lab 2.

Checkpoints 1 & 2 for Lab 1 have been posted on the calendar. Checkpoint 3 will be distributed in lab on Wednesday.

All students registered for Data Structures as of last week should have just received an email at their rpi.edu address with login & password information for the Computer Science department linux machines. This account will allow you to access the homework submission server that you need for lab tomorrow & to submit your homeworks.

If you registered for the class in the last few days and/or did not receive an email with your new account information, send email to the instructor and we will get you setup with an account ASAP.

Similarly, if you cannot access the LMS page for this course, send email to the instructor to be added to the LMS course page.
