Data Structures (Second Part) Lecture 1 Bong-Soo Sohn Assistant Professor School of Computer Science and Engineering Chung-Ang University

Course Overview Level : 2-th year CSE undergrad students Topics : Second part of Data Structures Review of Basic Data Structures Array, Linked List, Stack, Queue, Trees, and etc Advanced Data Structures Graph algorithms, Hashing, Search Trees, etc Basic Algorithms Complexity Analysis Sorting, Search, etc Objectives Understanding core concepts of various data structures Applying the data structures to actual programming Improve the ability of design and analysis of data structures and algorithms.

Textbook “Fundamentals of Data Structures in C”, Horowitz, Sahni, Anderson-Freed, 2 nd Edition, Silicon Press C++ version of the same book is also fine.

Evaluation Grade Percentage A : around 30% B : around 35% Midterm Exam : 30% Final Exam : 35% Assignments + Term Projects : 30% Class Participation : 5% You may get F grade if you miss (more than) ¼ of the whole classes Academic dishonesty (e.g. cheating, plagiarism, and etc.) will be taken seriously

Course Information Lecture Time : Mon 3, 4, Wed 3, 4 Lecture Room : Engineering 2 – 6514 English-Only Lecture English proficiency can be greatly improved by using and practicing English, not by just studying English. Lecture, Homework, Exam : 100% English Question : English Encouraged but Korean allowed. Project Presentation : English Presentaion Prefered (you will get bonus points) Professor Information Office : Engineering Office Tel : Office Hour : Thu 3pm-5pm, or individual appointment

Announcement Class Website Class information such as lecture notes can be accessible through this website We will also use MiniWeb for homework submission Programming Assignments We encourage to study and discuss together for doing programming assignments. However, you must do programming YOURSELF. You must not share any of source code with other students. Any kind of academic dishonesty will be taken seriously.
