Course Description

The course picks up from where CS 201 left by discussing concepts related to algorithmic efficiency on basic abstract data types and some sorting algorithms that utilize recursion. Then, the course introduces the abstract data types of trees, tables, priority queues, and graphs, and shows how one can implement them in C++ using fundamental data structures by emphasizing run-time complexity analysis.

Homework assignments will be posted on this page. Assignments are expected to be turned in by 23:55 on the due date. You should upload your solutions to the homework assignments using Moodle before the deadline.

For the late submissions, each student will be given one grace day for each homework assignment (with no deduction of points). If no submission is received within one day after the homework deadline, no submission will be accepted for that homework.

Please make sure you fully understand the Bilkent University Policy on Academic Honesty (in Turkish) and the Rules and Regulations of the Higher Education Council (YOK) (in Turkish). Cheating and plagiarism on exams and homework assignments will be punished according to these regulations.

Grading Policy

Midterm exam:40%
Final exam:40%

In order to be able to take the final exam, a student must

Otherwise, the student will receive the FZ grade.

The instructor also reserves the right to set other thresholds for passing grades.

Due to the YOK (Higher Education Council) regulations, we are taking attendance and will report it to the Department at the end of the semester.


When you are in doubt, ask. Use office hours. If you cannot visit us during office hours, you can always ask questions or arrange meetings by e-mail. Study regularly for the course and attend classes. Do your assignments on time and pay attention to the instructions for submitting assignments.
