Introduction

The repository contains content for CS2501 - Data Structures and Algorithms I at the University of Virginia. This course was originally part of the Computer Science department’s curriculum pilot. Starting in the Spring 2022 semester, it will become a new core course for all Computer Science Majors at UVa.

Contributing to this Repository

Updates to the repository are restricted to approved individuals only, to prevent anybody from messing with the slides right before a lecture. However, others can still contribute to this repository – to do so, take the following steps:

Create a github account, if you do not have one
Fork this repository: you can click on the “Fork” link in the upper right, or just click here
Clone your forked repository on to your local machine
Make any changes you want to your forked version, then commit and push your changes back to your forked repository
Create a pull request, following the instructions here

At that point, I will receive a notice that a change has been submitted, and I’ll look at it and hopefully accept it into the main repository.

When you want to bring in the updates from the main dsa1 github repository into your forked repository, you will need to follow the instructions here.

Course Description

A second course in computing with an emphasis on foundational data structures and program analysis. The course provides a comprehensive look at the Java programming language including object oriented programming, concurrency, inheritance / polymorphism. Additionally, foundational data structures and related algorithms / analysis are studied. These include Lists, Stacks, Queues, Trees, Hash Tables, and Priority Queues.

The ABET course objectives are:

Students will understand how to write programs in Java, including all basic structures (e.g., if-statements, loops, functions), recursion, objects, methods, inheritance / polymorphism, and exception throwing / handling.
Students will understand and implement several key data structures, required for a foundational education in computer science. These data structures include Vectors, Linked Lists, Stacks, Queues, Binary Search Trees, AVL Trees, Hash Tables, and Priority Queues.
Students will understand and be able to implement various sorting methods, including bubble sort, insertion sort, mergesort, quicksort, and heapsort.
Students will be able to understand and analyze program analysis using practical approaches (e.g., mergesort vs. quicksort) and theoretical approaches (e.g., balanced vs. unbalanced search trees). This will include both space and time complexity analyses.
Students will gather an abstract, and basic understanding of concurrency and associated issues (shared resources, etc.). Students will be able to implement simple multi-threaded programs in Java.
