Data Structure & Algorithm Lecture 1 – Course Introduction JJCAO Steal some from Prof. Yoram Moses
Course Introduction • Lecturer: Junjie Cao • Email: jjcao @ dlut.edu.cn • Webpage for the course: • http://www.jjcao.net/algorithmdatastructure.html • http://www.jjcao.net/c.html
Problem Solving by Computer input Manipulation output
Problem Solving by Computer input Algorithm output
What is an Algorithm? Data input Data manipulation Data output
Purpose of learning the course: Solving problems by computer • Data: information being analyzed e.g.: numbers, words, movies • Algorithm: a computational procedure for solving a problem • Data structure: The way the data is organized
Objectives and Philosophy • Objectives • Scientist (thesis + research) • IT, even other job (interview + work) • Mathematician + programmer in short period • Coding with C++ • Design appropriatedata structures • Implement smart algorithms • Philosophy • Interest examples driven • Useful Problems driven • Practice makes perfect!
Preliminary Knowledge • Little programming background is acceptable • IDE: Visual C++ 2010 • Language: C++ • How to learn them now? • Learning by practice (homework assigned in this course)
讨论 • 各位目标 • 学好？ • 考试高分 • 编程高手 • 混学分？ • 应付考试 • 希望的技能 • C or C++? • Turbo C/C++ or Visual C/C++? • 授之以鱼，不如授之以渔 • Enjoy coding
Course Introduction • 48 hours / 3credits • Final Grade = 30%*(Overall grade) +70% *(Score on Final Exam) • Overall grade: attendance, homework, midterm exam • 不允许抄袭！
