CSSE230 – Data Structures and Algorithms

Spring 2020-21 (aka 202130)

Schedule Overview

All non-Moodle web pages for the course are available from this index page.

This schedule page will begin with the schedule from a previous term, which will be updated as we go. We plan to update assignments and readings at least a week in advance. We’ll update daily schedules and slides just before class.

Preparation is to be completed before the class session.

Unless otherwise noted, all assignments are due at 11:00 PM on the day indicated.

Schedule last updated Wed Feb 17.
