About the Course

A good algorithm usually comes together with a set of good data structures that allow the algorithm to manipulate the data efficiently. In this course, we consider the common data structures that are used in various computational problems. You will learn how these data structures are implemented in different programming languages and will practice implementing them in our programming assignments. This will help you to understand what is going on inside a particular built-in implementation of a data structure and what to expect from it. You will also learn typical use cases for these data structures. A few examples of questions that we are going to cover in this class are the following: 1. What is a good strategy of resizing a dynamic array? 2. How priority queues are implemented in C++, Java, and Python? 3. How to implement a hash table so that the amortized running time of all operations is O(1) on average? 4. What are good strategies to keep a binary tree balanced? You will also learn how services like Dropbox manage to upload some large files instantly and to save a lot of storage space!...

I think the course content and assignments were great. A suggestion though, it will be more helpful if there are more and varied corner cases that would save time spent in thinking and making cases.

it was a very good cource overall..but the only thing that bothered me was that the thing being taught verses the things being asked in assignments are very very different.!!

Neil and daniel's teaching was great compared with the other two lecturers. I am saying this because they have a very low voice which made me lose interest during the class.

The course is good for the beginner it makes the programmer to think all the test cases but instead there should be more no of questions as a part of programming assignment.

I don't understand the need for the lecturer to be in the video, it's actually kind of distracting. Also, more worked out examples of the algorithm would be helpful.

The lectures and Assignments were very synchronized. However, I felt that some of the portions could have been taught in a better way. Rest the course was awesome.

I've learnt a lot. The content is very interesting but a bit challenging. I had hard times accomplishing all the assignment and put much more work than I expected.

It's a fine course, you'll get a LOT of information but it's up to you to keep it. Personally, I would've liked more types of trees but anyways I am satisfied.

Week 1 to Week 4 Fabulous. Week 5 and 6, based on BST, failed to provide me with proper knowledge. Also couldn't understand AVL trees and Splay trees coding.

Very Interactive Instructors. Learned a lot from this course for my career opportunities. Assignments aptly analyzed the understanding of the subject.

Course materials are very smartly designed but some of the problems are too difficult for a beginner, though the solution could be very smart.

Great course with in-depth explanation of the concepts and adequate quizzes and assignments which takes care of all the possible scenarios.

Material was great. Only issue was unit testing of programming assignments. The template code should have associated template unit tests.

Great course! however, if they provide additional materials to boost your coding style with STL libraries, the course would be top notch.

Very good. I feel the discussion forums could be a little more active and responsive, but I really enjoyed the course and learned a lot

The last two weeks' content may need to be revised to provide a better learning experience. To me, it seems a little bit too fast.

This course has only one weak point that is its mentors and teaching staff who are not actively helping on discussion forums.

More exercise will be better. It will be good you mention red-black tree segment and interval trees B and B+ trees

Overall the course is good. The last two weeks on AVL and

Splay trees need more examples and felt a bit rushed.
