Welcome! CSCI 0200 centers around data structures, the design and high-level analysis of algorithms for performance and social-impacts, and good programming practices using a combination of object-oriented (OO) and functional programming (FP). Each of the prereq courses (111, 112, 150, 170, or 190) teaches one of these two programming styles; in the first two weeks of the course, youâll learn the foundations of the other style so we can build on both throughout the semester.
This site is for the Spring 2026 offering. If you need materials from an earlier semester, see the previous offerings page.
Lecture Logistics
We meet on MWF 11-11:50pm in Salomon DECI. Lectures involve several exercises in which you will work on a problem with your neighbor before we come back together to go over questions. Most of the lectures are better-suited to pencil and paper notes than coding along, but you are welcome to code along if you wish.
We meet together as one group on January 21st. From January 23rd to February 2nd, we will meet as two separate tracks to cover the language foundations:
- Coming from CS0150? You will work with Prof. Nelson in Salomon DECI.
- Coming from CS111/112/170/190? You will work with Prof. DeMarinis in Sydney Frank Hall, Room 220 (Marcuvitz Auditorium).
Starting February 4th, weâll all be back together as one lecture section in Salomon DECI!
Communications
We will be taking questions in real time during class via Ed Discussions. If you have the course in your cart, you should have access to Ed and the lecture recordings in the Canvas Media Library.
Post questions on Ed. Personal or registration-based questions should be sent to Nick and Tim at cs200-profs@brown.edu. This is a dedicated course inbox that helps the Profs keep track of mail and manage it together.
Exams
There will be three pencil-and-paper exams this semester:
- Exam 1 will be 6-8pm on Wednesday, February 18th
- Exam 2 will be 6-8pm on Wednesday, March 18th
- The final will be 9am-noon on Saturday, May 9th
Barring significant extenuating circumstances or taking the course off campus, you must take these exams in person. Having booked early flights home will not count.
