CS206: Data Structures, Bryn Mawr College

Douglas Blank
Computer Science Department
Spring 2013


This course provides an introduction to the fundamental algorithms and data structures of computer science: sorting, searching, recursion, lists, stacks, queues, trees, graphs, and dictionaries. It also provides an introduction to the analysis of algorithms. Prerequisite: CMSC 205 or 110, or permission of instructor.

We will be using the language Java for this course. In addition, we will be using a series of environments for accessing Java, including:

We will be doing much of our work in Linux, and will gain understanding of the underlying mechanisms of compiling Java. For this, you will need a Linux account that I will provide. You (and the world) will also be able to access Java applets that you will write through a computer science computer (TBA).
