====== 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。

====== Pre-requisite and Enrollment policy ======
Pre-requisite: CSCI1110 or 1120 or 1130 or 1510 or 1520 or 1530 or 1540 or ENGG1110 or ESTR1100 or ESTR1102 or ESTR1002 or its equivalent. For senior-year entrants, the prerequisite will be waived.  Students are also expected to have basic knowledge in Linux command line.

If you have not used Linux command line interface before, you can consider the following online course from Udacity.

===== Programming Midterm Matters =====
  - The programming midterm is an open-book and open-notes examination.  You may bring what you can carry on printed (hard copy) materials.  You MUST not take anything that can record program code electronically to the examination venue.  You will not need a calculator for any calculation.
  - The operation system will be Ubuntu. And the computer configuration will have these basic editors:
    - vi/vim
    - emacs
    - gedit
    - nano
  - You can use all the functions provided by standard C library as long as you include the header file.
  - This system includes GDB for debugging. You need to work on Terminal in order to use it.
  - If you would like to have other editors, you MUST send an email to the instructor and TAs no later than 2 weeks before the examination date and it will be subject to approval to be included on the computer system.
  - You should arrive at the venue 30 minutes before the starting time on the day of the examination to receive your account information and check the system.
  - 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.
  - You should work on Problem #1 first and then others afterward. They are in increasing difficulties as judged by the instructor.
  - You MUST complete one problem in order not to fail the course.
  - Anyone who attempts to spam the server either through excessive submissions, allocating a large amount of unnecessary memory, etc. will be penalized severely.
  - If you leave early from the examination without informing TA, you will not be able to come back to the examination.

===== Written Midterm Matters =====
  - The midterm will test your knowledge of the materials up to Homework #3, that will be to include Heaps.
  - Answer all questions using the answer booklet. There will be more available at the venue if needed.
  - You can bring one sheet (A4, both sides) of notes. Calculator is not required. No electronics are allowed.
  - Write legibly. Anything we cannot decipher will be considered incorrect.

====== FAQ ======
  - **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, the inclusion of others' works or results without citation in assignments and reports is also regarded as plagiarism with a 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.
  - **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.
  - **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 [[http://www.acm.org/crossroads/xrds7-5/contests.html|this site]] for more information.
  - **Q: What does error message 'Restricted Function' mean in online judge?**\\ A: There is no standard definition of "Restricted Function". One general accepted guideline is that any code which may threat the system should not be executed. More specifically, any functions which are not needed when solving the problem should not be called. There are several possible reasons: 1. Using file-operating functions which are not allowed; 2. Mis-usage of pointers or malloc(); 3. Using system('pause').
  - **Q: Why can't I pass the judge even though I've passed all of my own test cases on my own computer?**\\ A: First, it is very common so there is no need to be frustrated. Your test cases may be not good or large enough. Here we provide three suggestions: 1. use array instead of linked list as long as it is possible; 2. declare more space (usually 10 more is enough) for arrays, e.g., declare 1010 in length when the maximum n is 1,000; 3. be aware of boundary cases, e.g., n=0, negative number, null pointer, etc.
  - **Q:  Return "not a text file" when submitting the code. **\\ A1:Delete all the comments in your code. \\ A2: You may not set up your account. Set up your account following the instructions of the second tutorial "{{:teaching:csci2100:2016:tutorial2_oj_new.pdf|Online Judge System}}" (8th page, Account Preparation).
  - **Q: "compile error in online judge system" but compile successfully in own PC. **\\ A: use notepad++ to convert the file into UNIX format. 1. Encoding -> Convert to ANSI. 2. Edit -> EOL Conversion -> Unix(LF)
  - **Q: Can not receive the email after submitting successfully. **\\ A: The system may send the email for you after a while not immediately.
  - **Q: Get wrong answer in the system but get correct answer in local PC. **\\ A: run the c file in UNIX to check the answer. 1. gcc -o hello hello.c 2. ./hello 
  - **Q: What is the meaning of the reply message 'Presentation Error'. **\\ A1: This may be because of the lack or abuse of '\n'. \\ A2: Make sure the return(0) if you define your main function return an integer; This will print a separate line, i.e. a line after your actual output :). **From Julius**.
  - **Q: Can I declare and initialize variables in the for loop？**\\ A: Declaring and initializing variables in the for loop is not allowed in the judge. 
  - **Q: Tips **\\ A: Defining the size of the array using a variable is not allowed.  You can use a constant instead. Actually, this is not necessary to define a two-dimension array. You can read and output line by line.
