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.

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 .

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!

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.

Interesting and hard (but possible to solve) challenges. All necessary information to solve a problem can be found in the lectures. The theoretical part is minimal but enough to start solve advanced problems. That's why I love this course more than others ever!

It is a must course for anyone who wants to excel in computer science field, and this course will help in every possible way from easy explanation of topics to effective assessment along with helpful discussions.

Thanks for creating such a wonderful course.

Lots to learn and it's fun to learn from different teachers. Very heavy (and high quality) course if one wants to do proper justice to all the materials presented (especially hashing and trees... Week 3 onwards). A worthy investment . Enjoyed it immensely.

Nice course, It was bit difficult for me. I think I will have to go over the few lectures again soon. Problems were very cool, these took lots of hour head down. Thanks all lecturers, specially Daniel M Kane and Alexander S. Kulikov. Loved your lectures.

Similar to the first course in this Specialization, a great course on algorithms and their applications. Frustrating at times, but I definitely recommend this course (and the others) if you are serious about implementing algorithms for whatever purpose.

I appreciate the fact that our lecturer put a lot of efforts in Practice case study and Coding practice along with most of the theories covered. This is one of the best course I've learned, which help me to understand and "digest" things in easy ways.

Great course, hard and challenging.

Couple comments.

Please use pen during lectures easier to follow and understand .

Some assignments require more then 8 hours to complete so please add to description of the course

(don't make assignment easier)

State-of-the-art programming techniques with detailed explanation of methodologies and why they are more efficient than basic solutions. Difficulty of the programming assignments ranges from easy practice exercises to really challenging problems.
