The course is detailed, challenging and practical. Unlike a lot of other MOOCs which dilute the rigor of the course way below university standards, this course has coding assignments, which if done honestly, will definitely help anyone REALLY understand the intricacies behind all the data structures and algorithms that we are taught. I recommend this course to a lot of my friends too!

Excellent course, I learnt a lot.

The programming assignments are really challenging, so assume the course to take way longer than the estimated amount.

If you still decide to go through with it, the lectures are great, and the subjects are really interesting.

I'm amazed at the solutions past programmers have found to such complex problems as the ones presented throughout the course.

Great course! As soon as you'll understand how the splay tree works and use a hint from the assignment, the rope problem (the best so far) will no longer be a problem. The course could have been improved though by giving a brief overview of B-trees and Red-Black trees. Anyways, thanks to all the instructors for their hard work and good luck to the all the learners!

This course helps me fully understand how hash is implemented in most programming languages. How to build something like dropbox.... The Rope data structure is the most challenge I've met for a long time. Many thanks to creators help me get a chance to understand Rope data structure, then I can understand what Xi- text editor platform that Google is writing about.

A) An eye opener course in my regards which is really well curated and organized.

B) I had gone had to learn a good deal of knowledge and software wisdom from this course that I highly RECOMMEND this to others.

C) Enroll into it and try to finish the assignments on time and I am sure you will end up seeing the results yourself...

Great course - the homework problems were really helpful for cementing concepts. However, I did feel that the difficulty of the homework problems did not increase with the progress of the course. I think that it would have been very reasonable to increase the difficulty of the homework assignments as the course progressed. Otherwise, great overall course.

I think this is one of the best courses out there in terms of the rigour as well as the quality of the content. The instructors take great care to actually explain how the data structures work internally, complete with mathematical proofs wherever necessary. The assignments are also very good and help to solidify the understanding of the concepts.

An excellent course for those who is willing to learn basic concepts and practice their programming skills in data structures. Students would learn a lot after finishing the assignments. More over, slides provided are extremely clear and helpful.

However, it seems that the forum is not active, most questions and answers were posted months ago.

One of the best courses I've taken so far. I had to complete it extremely quickly because I had no time to do it and it was a really good experience. The intense programming assignments and amazing explanations were really enjoyable. After so long not programming properly, I spent an entire day at my laptop for these assignments and loved it.

Really awesome Course , Must take it as a software Engineer and if you have already learned these things , It will open your eyes and make you correct your mistakes.

Simple explanations in videos and covering all intermediate data structures.

Problems are also good companion to the course content and allowing us to implement in many languages .

It was a great course and I've learned a lot. I've voted 5 stars because it is the maximum number. professional Instructors and they know how things work, English is very clear and understandable. This course worth the effort and time that you'll spend on it. Thanks Coursera and University of California San Diego for such a great course.

Excellent course. Actually my university can not complete Data Structure Due to this COVID-19. But this course has given the perfect opportunity to acquire the knowledge of Data Structures and Algorithms. The problems were a bit challenging but I enjoyed it a lot. I would recommend everyone do this course who loves programming. Thanks!

really good course , advanced problems will improve your skills to think and use the data structure , although it is obvious where to think as it is application on the week lesson so maybe if the problems are more general will be better.

still , this course improved my skill to implement data structure and understand it deeply . thanks

A thorough course covering many fundamental data structures and some very impressive applications.

The assignments are challenging but extremely satisfying. I especially enjoyed implementing a rolling hash and working with binary trees.

It covered more material in depth than my data structures university subject.

A very good course if you want to learn how we organize data in such a way that we can perform specific operations with low computing cost. This course is language agnostic so it becomes more about learning the fundamental structures and less about troubleshooting the language you use. Very good course!

Perhaps the videos on AVL Trees (Rotations basically) and Splay Trees can be enhanced to give a more thorough grounding. I had to refer to many sources to get the concepts grilled into my head. But it has been an awesome experience so far in this specialization. Kudos to the team behind this.

Helped summarize the basics for a newbie like me. Glad I took it :) Recommended.

Although, I do recommend some more material on the last two weeks - I loved the concepts that were taught, but I feel there could have been more lectures on BST applications, given how powerful they are!

Thanks!

One of the best courses on Data Structures. I am learning a lot in this specialization. Though, some of the videos could be better in terms of presenters. Some of the presenters seem to just read of paper without really understanding the context. But anyway, it is really valuable course.

Amazing explanation of Queue, Hashing, Disjoint-set, Dynamic Array, etc. with their basic operations. An amazing way of IP address representation I learned in Hashing I paste the IP in a single decimal digit in my browser of some website with "http://<single decimal IP>" it's working.

The course is excellent. I learnt a lot from it, and would continue to learn even after receiving certificate.

One small suggestion : It would be great if we can get the actual test case for which our program has failed. It would help in debugging.

Thanks a lot for excellent experience.

As every other course on this series the programming assignments are excellent. I ignore lectures and go directly to the assignments. The lecture are very monotonous in tone. Its really hard to understand the accent. I usually learn topics elsewhere and attempt the assignments here.

Very interesting class, I learned a lot, about implementation and real life applications.

Like the previous class, there is many assignments to practice, so I really recommend to pick up a programming language that you are comfortable with, if you want to move forward at a good pace.

Personally, this course is interesting and essential for the learner to proceed to other more advanced courses, either within this specialisation or not. There is only one suggestion that it will be better if the instructors can provide more details of the pseudo codes.

This course provides very good insights into data structures. The instructors are very good and gave concise and clear explanations for all the concepts. I have enjoyed working on all the assignments. The were challenging and made me apply all the concepts I learned .

Really liked this course - it is a comprehensive overview of basic data structures. Programming assignments are mostly to implement some data structure and use it to solve problem, but there are some challenging advanced tasks, which it was very interesting to do.
