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 online 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.

The course is well structured and smooth. The content is rich and really covers the important stuff in data structures.

However, still, the problems come from the interface and the grading system, please Coursera you can do better than this in the discussion forum and the grader.

Another good course, though the last two weeks were a lot harder to follow than the prior ones. Not because the material was that much harder, but the lectures and homeworks were less clear (a lot of descriptions of how to do various operations without explaining why).

I liked the course overall. It helped me a lot, and I saw the positive effects in a short period of time. But please change the hashmap course with something else. It was pain to watch since the instructor just read some theoretical stuff from the slides. Thanks.

This course is very good for those who are trying to learn Data structure. well you have to have some basic knowledge of the programming languages like python, c++, java for the programming assignments.

Very good course for intermediate level. Thank you so much!

First I want to mention I didn't waste my time with this course.

This course help me a lot to clear my doubts and also learned modern applications, concept of DS in various fields as well throughout this course.

I appreciate help from Mentors and Coursera too.

It is a very useful course .

I had some problems with implementing the concepts as codes , I think the assignments have to be more easy to code without losing the main idea of them.

I am so happy and thankful for every teacher , they were all amazing :)

First 3 weeks were great (as in first course of specialization), but material in last two weeks was very hard to understand. Feels some mess in explanations compared to other part of the course. Maybe its because of difficulty of the last weeks topics.

Generally good, Russian lectures's pseudo-code is kind of giving me a hard time, guess I'm just not used to that style of notation, content of week 6 rises a bit steep, people might have hard time keeping up. Problem set was good though.

It's very fun to learn, and the explanations are very clear. But there are some parts that the explanations are still not very clear and I had to rewatch it multiple times to understand it. But overall, the course is very good!

this course has some good video explanations on every topic and such relevant assignments which can be applied easily. but for me some what hard because I haven't tuck another course they subjected before this one.

Binary search trees were not explained very well. Programming assignments are usually very easy. Nevertheless, it is a very interesting course and the assignment do help to learn about the topics covered. Useful.

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!

Good content and assignments, but the explanations could have been clearer, especially for the BST and Splay Tree section. Also, I think it makes little sense to hide the tests.

Everything is great except week 6. One of the video has mistakes in its subtitles and the lecturer in this week don't make me feel comfortable to listen to him. His voice is bad!

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.
