CSE 30872 is an elective course in the Computer Science and Engineering program at the University of Notre Dame. This course encourages the development of practical programming and problem solving skills through extensive practice and guided learning. The bulk of the class revolves around solving brain-teaser and puzzle-type problems that often appear in programming contests, online challenges, and job interviews. Additionally, basic software engineering practices such as planning, debugging, testing, and source code management may be discussed.

Upon successful completion of this course, students will be able to:

  1. Parse a variety of inputs and model problems.

  2. Utilize appropriate data structures to represent and solve problems.

  3. Implement common problem solving techniques and algorithms.

  4. Employ modern software development methods and tools.

  5. Debug and test code within an automated testing environment.

Due Dates

All Readings and Challenges are to be submitted to your own private GitHub repository. Unless specified otherwise:

  • Readings are due before class on the Monday of each week.

  • Challenges are due at noon on the Saturday of each week.

The External Contest submissions are due at noon on Wednesday, December 8.



Students are expected to attend and contribute regularly in class. This means answering questions in class, participating in discussions, and helping other students.

Foreseeable absences should be discussed with the instructor ahead of time.


Recalling one of the tenets of the Hacker Ethic:

Hackers should be judged by their hacking, not criteria such as degrees, age, race, sex, or position.

Students are expected to be respectful of their fellow classmates and the instructional staff.

Students with Disabilities

Any student who has a documented disability and is registered with Disability Services should speak with the professor as soon as possible regarding accommodations. Students who are not registered should contact the Office of Disabilities.

Academic Honesty

Any academic misconduct in this course is considered a serious offense, and the strongest possible academic penalties will be pursued for such behavior. Students may discuss high-level ideas with other students, but at the time of implementation (i.e. programming), each person must do his/her own work. Use of the Internet as a reference is allowed but directly copying code or other information is cheating. It is cheating to copy, to allow another person to copy, all or part of an exam or a assignment, or to fake program output. It is also a violation of the Undergraduate Academic Code of Honor to observe and then fail to report academic dishonesty. You are responsible for the security and integrity of your own work.

Late Work

In the case of a serious illness or other excused absence, as defined by university policies, coursework submissions will be accepted late by the same number of days as the excused absence.

Otherwise, there is an automatic 25% late penalty for assignments turned in 12 hours pass the specified deadline.

Classroom Recording

This course will be recorded using Zoom and Panopto. This system allows us to automatically record and distribute lectures to you in a secure environment. You can watch these recordings on your computer, tablet, or smartphone. In the course in Sakai, look for the "Panopto" tool on the left hand side of the course.

Because we will be recording in the classroom, your questions and comments may be recorded. Recordings typically only capture the front of the classroom, but if you have any concerns about your voice or image being recorded please speak to me to discuss your concerns. Except for faculty and staff who require access, no content will be shared with individuals outside of your course without your permission.

These recordings are jointly copyrighted by the University of Notre Dame and your instructor. Posting them to other websites (including YouTube, Facebook, SnapChat, etc.) or elsewhere without express, written permission may result in disciplinary action and possible civil prosecution.

CSE Guide to the Honor Code

For the assignments in this class, you may discuss with other students and consult printed and online resources. You may quote from books and online sources as long as you cite them properly. However, you may not look at another student's solution, and you may not copy any significant portions of other's solutions.

The following table summarizes how you may work with other students and use print/online sources:

Resources Solutions
Consulting Allowed Not Allowed
Copying Cite Not Allowed

See the CSE Guide to the Honor Code for definitions of the above terms.

If an instructor sees behavior that is, in his judgement, academically dishonest, he is required to file either an Honor Code Violation Report or a formal report to the College of Engineering Honesty Committee.

Health and Safety Protocols

In this class, as elsewhere on campus, students must comply with all University health and safety protocols, including:

  • Students who are not fully vaccinated must wear masks inside campus buildings.
  • Students are expected to carry a mask at all times.
  • Students are to be considerate and understanding of the medical needs and personal beliefs of others.

We are part of a community of learning in which compassionate care for one another is part of our spiritual and social charter. Consequently, compliance with these protocols is an expectation for everyone enrolled in this course. If a student refuses to comply with the University’s health and safety protocols, the student must leave the classroom and will earn an unexcused absence for the class period and any associated assignments/assessments for the day. Persistent deviation from expected health and safety guidelines may be considered a violation of the University’s "Standards of Conduct,” as articulated in du Lac: A Guide for Student Life, and will be referred accordingly.
