  8. 28 April 2010. Important information for the final examination. The final examination will be a closed book and closed note written examination. You will not require to have a calculator and need only to bring writing instruments and your ID.

    The final examination covers ALL materials from the course, but emphasis will be placed on materials since the written midterm. There is not a programming component to the final examination.

    You may find the marks for all your work here. Please make sure that your marks are accurately reflected by May 1, 2010. We will not change any marks from work before the final examination after May 1, 2010.
  9. 9 June 2010. URGENT and IMPORTANT! We have discovered mistakes regarding to the on-line judge system. The mistakes are setting the system deadline one day before the actual deadline. In light of this, many valid and correct submissions on the day of the actual deadline have been recorded incorrectly. These errors have basically lowered the scores for at least 20 students. We have corrected these mistakes and revised the corresponding grades accordingly. The good news is that these changes have not led to any grades being lowered. Here is the final scores (latest) and here is the original scores (earlier) for your reference.

Course Description

The concept of abstract data types and the advantages of data abstraction are introduced. Various commonly used abstract data types including vector, list, stack, queue, tree, and set and their implementations using different data structures (array, pointer based structures, linked list, 2-3 tree, B-tree, etc.) will be discussed. Sample applications such as searching, sorting, etc. will also be used to illustrate the use of data abstraction in computer programming. Analysis of the performance of searching and sorting algorithms. Application of data structure principles.

本科介紹抽象數據類型之概念及數據抽象化的優點。並討論多種常用的抽象數據類型,包括向量、表格、堆棧、隊列、樹形;集(合)和利用不同的數據結構(例如:陣列、指示字為基的結構、連接表、2-3樹形、B樹形等)作出的實踐。更以實例(例如:檢索、排序等)來說明數據抽象化在計算機程序設計上的應用。並討論檢索與排序算法及數據結構之應用。

Programming
10 April 2010
9:00 am to 1:00 pm
Room 924 The CSC2100B Programming Midterm will be
held in room 924 of the HSH Engineering Building
from 9:30 am sharp to 1:00 pm. We will let people in around 9:00 am.

You can bring print outs of previous programming homework assignments. The scope is all programming assignments.
Final Examination TBD TBD The final examination covers all materials presented in the class
but emphasizes more on the materials after the midterm. This is a closed book examination.

Programming Midterm Matters

  1. The programming midterm is an open-book and open-notes examination. You may bring what you can carry on printed (hard copy) materials to room 924. You MUST not take anything that can record program code electronically to the examination venue. You will not need a calculator for any calculation.
  2. The computer configuration will have these basic editors:
    1. VI
    2. Visual Studio
    3. Notepad++
  3. If you would like to have other editors, you MUST send an email to the instructor and TAs no later than 7 days before the examination date and it will be subject to approval to be included on the computer system.
  4. You should arrive to the venue before 9:30 am on the day of the examination to receive your information and check the system.
  5. The examination will begin when the Chief TA starts the clock and will end when the Chief TA stops the clock, which is usually three hours after the starting time including any missing time due to technical and other difficulties.
  6. You should work on Problem #1 first and then others afterwards. They are in increasing difficulties as judged by the instructor.
  7. You MUST complete one problem in order not to fail the course.
  8. Anyone who attempts to spam the server either through excessive submissions, allocating large amount of unnecessary memory, etc. will be penalized severely.
  9. If you leave early from the examination, you will not be able to come back to the examination.

Written Midterm Matters

  1. The midterm will test your knowledge of the materials upto Assignment #3, that will be to include Trees.
  2. You will be assigned the venue according to your last name.
  3. Answer all questions using the answer booklet. There will be more available at the venue if needed.
  4. Write legibly. Anything we cannot decipher will be considered incorrect.

FAQ

  1. Q: What is departmental guideline for plagiarism?
    A: If a student is found plagiarizing, his/her case will be reported to the Department Discipline Committee. If the case is proven after deliberation, the student will automatically fail the course in which he/she committed plagiarism. The definition of plagiarism includes copying of the whole or parts of written assignments, programming exercises, reports, quiz papers, mid-term examinations. The penalty will apply to both the one who copies the work and the one whose work is being copied, unless the latter can prove his/her work has been copied unwittingly. Furthermore, inclusion of others' works or results without citation in assignments and reports is also regarded as plagiarism with similar penalty to the offender. A student caught plagiarizing during tests or examinations will be reported to the Faculty Office and appropriate disciplinary authorities for further action, in addition to failing the course.
  2. Q: What is ACM ICPC?
    A: Association of Computer Machinery International Collegiate Programming Contest. Teams from CUHK have done quite well in the previous years. More information on the CSE's programming team can be found at http://www.cse.cuhk.edu.hk/~acmprog.
  3. Q: What are some of the common mistakes made in online and real-time contest?
    A: There are a few common mistakes. Please check out this site for more information.
