課程概述

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 like this course very much! Rope is the cleverest task I have ever done! Of course, I hope in future I will work on even more difficult problems, but this is pretty good already for me as a student!

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.

Even though I am already aware of all these data structures, I gained some more in-depth knowledge about them, also got introduced to splay trees. definitely worth a try,some of the assignments are really good.

Thanks for the course. Content is good and videos are very well done. Only problem is that the assignment problems were gruelling and unfortunately it is hard to get one-to-one contact for help if you get stuck

The course is overall quite challenging. The explanations certainly could have been better with a little increase in diagramming stuff out. I had to refer multiple resources to fully understand the concepts.

great course with challenging assignments, the problem with the course is the accent of some of the lecturers which make the lecture harder to follow also not enough examples in the lectures

Great course, tests you on a wide spectrum of difficulty. The assignments are crafted to help students learn gradually and build their confidence over Data Structure concepts efficiently.

In depth mathematical analysis and implementation of important Data Structures. This is a very good course for programmers looking to solve computational problems with first principles.

Overall, it's good. But some chapters like the binary search tree and hash table, the instructions are now very heuristic. I can only understand the content after reading the textbook.

The course was interesting and challenging for me. The main problem that I had with this course was lack of communication with the teachers. But all the tasks and lectures were great!

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.

great course; challenging and I learnt a lot. only problem is that its quite long, I found it hard to keep my momentum going all the way through!

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

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.

it was an awesome specially the dsu and heap sessions , but i think that the second week was very hard and wasn't useful for me ,, thanks

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.
