General course information


A survey of the major types of structures in programs used to handle data, including arrays, lists, stacks, queues, trees, etc. Methods for data organization and access will be covered across data structures, and studied for their memory footprints and temporal efficiencies. This course builds on principles in discrete mathematics and in fundamental programming practices.


CISC2000/2010 Computer Science II and Lab.

Teaching mode (tentative)

The teaching will be hybrid — that is, it includes both synchronous and asynchronous instruction. Synchronous lectures will be given via Zoom for students who opt for online classes, whereas in-person lectures will be given to students who opt for face-to-face teaching. Asynchronous instruction will be in the format of pre-recorded videos. Before each scheduled lecture, readings and pre-recorded videos for the lecture will be posted on course website. Students should read and watch these materials before the lecture. The synchronous lectures will include illustration of key concepts, hands-on instruction, discussion of related topics, and Q&A. After each synchronous lecture, the screencast will be posted on course website, and if necessary, more videos will be uploaded for clarification and elaboration. All videos will include only the instructor’s picture and voice.

Depending on the feedback from students and the possible policy changes from the department/college/university, the teaching mode may be changed. The instructor will not make any changes without notifying students in advance.

Asking questions and getting help

The best ways to ask questions outside of class are on Piazza and at office hours. Unless your Piazza post needs to be private, please make the post public, since other students may be interested in the question and answer. If you prefer, you can post anonymously

To contact the instructor privately, please make a private Piazza post instead of sending email. To set up an appointment outside of office hours, create a private post to the instructor including your available times for at least three forthcoming weekdays.

Assignments & exams

There will be weekly labs, homeworks, and/or projects. Github Classroom will be used to manage all assignments, and you will use Git to turn in everything electronically. Labs will be given full credit for passing all of our autograder tests while homeworks will receive full credit for showing “reasonable effort”. Programming projects will have autograder tests and some other tests. We encourage you to write your own tests to provide a more complete test suite.

You must do all assignments individually. You may discuss with other students at a high level, but not at the level of developing algorithms or pseudocode together, and you shouldn’t develop or share any written or electronic content; any of these activities can lead to similar code. Most importantly, you must NEVER show, share, or send your code to anyone else (nor receive anyone else’s) for any reason. Official university policy will be followed in cases of academic dishonesty.

All assignments are due by 11:59:59 PM on the due day. No exceptions will be made to this deadline: if you submit at 12:00:01 AM, your submission will be considered to be late and you will receive zero points for this assignment. Please plan your time carefully and do not submit in the last minute.

There will be one midterm exam and one final exam. Both exams will be online and you should use Git to submit your answers.


The percentages given below are guidelines for both the student and instructor and may be changed as needed to reflect circumstances in the course. Any changes that occur are likely to be minor.

Class participation 5%
Labs & homeworks 55%
Projects 20%
Midterm exam 10%
Final exam 10%

Final grade is based on the course average: A: 100-90, B: less than 90-80, C: less than 80-70, D: less than 70-60, F: less than 60-0.
