Focuses on the common structures used to store data and the standard algorithms for manipulating them. Standard data structures include lists, stacks, queues, trees, heaps, hash tables, and graphs. Standard algorithms include searching, sorting, and traversals. Along with implementation details, students will learn to analyze the time and space efficiency of algorithms and how to select appropriate data structures and algorithms for a specific application. In homework, labs, and programming projects, students will implement their own data structures and make use of existing libraries to solve a variety of computational problems.

|Weekly Course Schedule||
The following structure will rarely change.
In order to provide as much help as possible to you as you work on assignments in this course, the CS Department has hired upper-level CS students to work as TAs over Zoom in the evenings. You are strongly encouraged to take advantage of this resource.
|Class time problem sessions||
The lectures will be run in a "flipped" manner. This means that class time will not actually be used for
lectures. Instead, lectures that introduce new material will be available as videos for you to
watch online or to
download and watch at your convenience offline.
The class time will be devoted to the following:
The learning goals for the lecture and lab are the same -- both are
meant to work together to accomplish the goals for the course as a
whole. They are
|Labs and Projects||
The work in lab will lead into and be part of the week's project. Labs will also count significantly towards participation.
During each lab, the instructor will not be able to answer questions about any projects until you have completed the tasks for that lab.
Programming projects involve completing more significant programs as well as a writeup describing the work completed in the project.
There will be regular opportunities for you to practice what you have learned and to demonstrate your accomplishments.
The course grade will be determined as follows:
There will be an online final exam during finals week. You will have a 24-hour window in which to take it. There are no make-ups.
It should go without saying that you should back up any files related to this course. If the code you submit to us is somehow lost (through your fault or our fault), I must be able to get another copy from you. I suggest keeping your CS151 labs and projects on Google Drive, Dropbox, or Microsoft OneDrive, but not in a public place. That way, you have a backup stored in the cloud.
There is no required textbook for this course. All lecture materials and code from class will be posted on Moodle.There are also lots of on-line resources available.
Here are some examples of free online data structures textbooks using Java:
|How to succeed||
Labs and Projects: Come to lab ready to focus on the new project. Ask the instructor and TAs for help if you need it.
Quizzes: Study for the quizzes by doing the homework, participating in the problem sessions, and watching the lecture videos. As mentioned above, we will drop the lowest two quiz grades. Therefore, if you have to miss a quiz or if you make a silly mistake once or twice, it won't affect your grade.
Short homeworks: Try them. You will receive full credit as long as you make an honest attempt to complete every question and submit your response to the Moodle drop box before the deadline. Please ask or email questions if something isn't clear. There is no credit for late homeworks because we will go over the answers in the next class.
Participation: Speak up in class. Come to office hours. Ask your instructors or TAs for help.
Final Exam: The final exam will be similar to a large set of quizzes (but written from a more holistic perspective) except it may also have a few longer questions. The best way to study for the final exam is to retake all of the old quizzes. Also, read through your notes and all material supplied on the course Moodle page and make sure you understand everything in them.
|Collaboration, Academic honesty||
Computer science, both academically and professionally, is a collaborative discipline. In any collaboration, however, all parties are expected to make their own contributions and to generously credit the contributions of others. In our class, therefore, collaboration on assignments is encouraged, but you as an individual are responsible for understanding all the material in the assignment and doing your own work. Always strive to do your best, give generous credit to others, start early, and seek help early from both your professors and classmates.
The following rules are intended to help you get the most out of your education and to clarify the line between honest and dishonest work. We reserve the right to ask you to verbally explain the reasoning behind any answer or code that you turn in and to modify your project grade based on your answers. It is vitally important that you turn in work that is your own. We do use automated plagiarism detection software, so please be sure to abide by these, rather minimal, rules. Reports of academic dishonesty are handled by an academic review board and a finding of academic dishonesty may result in significant sanctions. For more details on Colby's Academic Integrity policies and procedures, see colby.edu/academicintegrity.
