CSci 2101 Data Structures.

The syllabus below is somewhat approximate. Dates, topics, assigned reading, and problem set due dates are subject to change. All changes in assigned reading and due dates will be announced in class (and occasionally by e-mail). While I will do my best to update the web site accordingly, it is a student's responsibility to keep track of the problem set due dates and reading assignments. If you are not sure about due dates, please don't hesitate to ask.

Note that the date for the midterm exams are set and will not change. If you have a conflict with this date, please let me know right away.

Reading sources (see the 2101 home page for complete references):

If you are not sure about the source of reading, please ask right away.

You are welcome to use other textbooks and/or online materials. If such materials made a substantial contribution to your homework assignment, please acknowledge the source and the exact contribution. If you plan to use extra sources for an in-class or a take-home exam, please get my OK first. Otherwise such a use would be considered cheating.

Problem sets are submitted electronically (by e-mail) and are usually due at 8pm on the due date. Please see the Assignments page for guidelines and specific due dates.

A take-home exam must be submitted on time, otherwise it will not be graded.

Individual vs. group assignments.

Homework assignments are individual work, unless specified otherwise.


Lab assignments and submission instructions are posted on the Lab web page.
