This is an introductory course in data structures and programming, meant for students who have not had a formal course in programming, algorithms and data structures as part of their undergraduate program. The course will introduce of problem solving using programs and design of algorithms and their complexity. It will review elementary data structures such as Arrays, Stack, Queues, Maps, and related algorithms for manipulating the data structures. It will also discuss sorting and searching techniques, and their complexity. We will also briefly explore more advanced data structures such as graphs and graph algorithms, balanced trees, tries and heaps. A overview of parallelism and concurrent data structures will also be given toward the end of the course. Algorithmic strategies such as greedy Algorithms, Dynamic Programming and Divide and Conquer will also form part of the learning.
These lectures will be complemented by lab sessions that introduce object oriented programming with C++, implementing the data structures using C++, and also using standard data structure libraries present in the language. There will be periodic programming assignments to validate these concepts.
Topics in this course are loosely based on IEEE and ACM’s Curriculum Guidelines for Undergraduate Degree Programs in Computer Engineering, a draft of which is available online.
This course is a precursor to more advanced courses like E0 251: Data Structures and Algorithms, E0 225: Design and Analysis of Algorithms, DS 292: High Performance Computing, DS 295: Parallel Programming, and DS 256: Scalable Systems for Data Science. Students already familiar with data structures and programming may prefer those rather than this introductory course.
This is an introductory course on data structures and programming. So the pre-requisites are minimal — knowing to operate a computer, preferable Linux, using the commandline, installing packages, using SSH, using a text editor or IDE — but students are expected to pick up the skills rapidly as part of the lab sessions.
The total assessment score for the course is based on a 1000 point scale. Of this, the weightage to different activities will be as follows:
|40% Homework||About 7 programming assignments of 50-100 points each (400 points)|
|10% Online Coding||Self-selected programming assignments on online coding website (CodeChef) (100 points)|
|50% Exams||One Mid-term (200 points) and one Final (300 points) exam.|
Students must uphold IISc’s Academic Integrity guidelines. We have a zero-tolerance policy for cheating and unethical behavior in this course and failure to follow these guidelines will lead to sanctions and penalties. This includes a reduced or failing grade in the course, and recurrent academic violations will be reported to the Institute and may lead to an expulsion.
Learning takes place both within and outside the class. Hence, discussions between students and reference to online material is encouraged as part of the course to achieve the intended learning objectives. However, while you may learn from any valid source, you must form your own ideas and complete problems and assignments by yourself. All works submitted by the student as part of their academic assessment must be their own.
- Verbatim reproduction of material from external sources (web pages, books, papers, etc.) is not acceptable. If you are paraphrasing external content (or even your own prior work) or were otherwise influenced by them while completing your assignments, projects or exams, you must clearly acknowledge them. When in doubt, add a citation!
- While you may discuss lecture topics and broad outlines of homework problems and projects with others, you cannot collaborate in completing the assignments, copy someone else’s solution or falsify results. You cannot use notes or unauthorized resources during exams, or copy from others. The narrow exception to collaboration is between team-mates when competing the project, and even there, the contribution of each team member for each project assignment should be clearly documented.
- Classroom Behavior
- Ensure that the course atmosphere, both in the class, outside and on the online forum, is conducive for learning. There are no “stupid” questions, so ask away. Actively participate in discussions but do not dominate or be abusive. Be considerate of your fellow students and avoid disruptive behavior.
