You are encouraged to collaborate in study groups. But you cannot directly copy or slightly change other students’ solutions or code

We use a computer program to automatically check if two assignments are similar (even if you make the variable names different, it can detect similar solutions). If so, you will be interviewed for possible violation.

Course Overview

A fundamental computer science course

- Essential for programming

- Essential for advanced courses like 271 A challenging course

- Intensive programming

- Intensive (mathematical and logic) thinking A fun course

Lots of thinking and clever solutions

Course Prerequisite

COMP103 or COMP104 Need to know C and C++ Visual Studio or other PC programming environment Good programming skills Translate pseudo-codes into codes Speedy review in the 1st week

COMP151 Not essential Highly recommended to be taken concurrently

Basic mathematical skills Solving recursive equations, manipulation of symbols,

etc. Computer architecture

Pointers, storage, memory access, etc.

Course Outline

C++ Review Algorithms and Analysis List, Stack, Queues Trees Hashing Sorting Graph

Overall Goal of the Course

From programmer to architect Learn to solve problems Algorithms and Programming go hand in

hand Learn to analyze your solutions

Lecture Format

Feel free to interrupt to ask questions Lectures:

Slides are available one day before the lecture It is important to attend the lectures (Not all materials

are covered in slides) Tutorials

Supplement the lectures Some important exercises Welcome to attend other labs if you miss the your

assigned session Programming and homework assignments

More rigorous problems to consolidate your knowledge

Assignments

Written Assignments (WA) Due by time specified Contact TAs directly for re-grades Re-grade requests will only be entertained within

1 week after the homework are handed back Programming Assignments (PA)

Submit it yourself through the assignment program

Run on PCs We will not handle porting problems

Late Policy

For written assignments, 20% will be deducted for one day late submissions. Assignments later than 1 day will not be accepted.
