CompSci 201: Data Structures & Algorithms (Sec 02)

Spring 2026

Time: Mon/Wed 3:05pm-4:20pm
Location: LSRC B101 (Love Auditorium)

IMPORTANT

This website is for Prof. Steiger's section 02 of CS 201. It has exactly the same lecture schedule, syllabus, and policies as in Prof. Astrachan's section 01. This website will have our section-specific content (slides, links, resources, etc.). Starting off this semester, the only differences are in our slides and the platforms that we will use to complete some assignments.

Course Overview

Analysis, use, and design of data structures and algorithms using an object-oriented language like Java to solve computational problems. Emphasis on abstraction including interfaces and abstract data types for lists, trees, sets, tables/maps, and graphs. Implementation and evaluation of programming techniques including recursion. Intuitive and rigorous analysis of algorithms.

For more information, please see the course syllabus.
