课程概述

A good algorithm usually comes together with a set of good data structures that allow the algorithm to manipulate the data efficiently. In this 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.

During this course, my experience was that the lectures and course notes did not seem to equip me to answer the quiz questions. While I was able to complete the practical assignments fine, I found the quizzes to be much harder and in some cases I needed to guess my way past. This may simply reflect a difficulty on my part to properly learn the material. Thanks to the authors for an interesting course, regardless!

Course content is ok, but some lectors are really boring in explaining mathematical details.

Tasks are pretty easy, and this is from algorithmic perspective, because from programming there are almost nothing to do.

And overall it feels that there are not so much info as for 5 weeks course. If it would cost lest, than it would be ok. But for 80$ I've expected more.

I completed the course, and liked the choice of topics and problems very much - thank you for your efforts! For the next version, I'd recommend having more "intuition" videos. Sort of like Andrew Ng does in his introductory ML video. Overall, the course was vey useful in giving a strong foundation of the fundamentals. thank you!

I have completed all the course and the quizzes also. but programming assignments are not completed due to the link of the assignments are expired. I kindly request you to please provide me Certificate of this course which is required for my college grading.

The course is great in theory while in practice they should provide solutions for the questions that we were unable to solve so as to help and benefit us in the future. Please consider this review and improve upon all other courses of this specialization.

Some lectures give very limited information to understand the topic. Therefore I had to watch other lectures on YouTube. Hashtables topic have much more lectures(5 hours) for 1 week. But Binary Search Trees are splitted into 2 weeks with the same hours.

For a beginner like me its totally going over the head. I mean i get the logic but if you guys can please give more code...

I am learning data structures for the first time and it is bit difficult for me to grasp it all and write codes in a week...

The course was little bit boring because of some of the speakers. It was little hard to understand their accent and along with that grasp everything needed.

Also the programming challenges I found a little hard but tried to do the best to solve.

The last part of this course is unsatisfied. It seems that the teacher in the last part is not very responsible for this course and he obviously has a bad preparation for this course.

Needed easier conceptual understanding considering an average student also please make the assignment questions more understanding rather than just submissions.

You should provide option to download failed test cases, then we can further develop our solution by solving edge case and improve our skills.

Some of the lectures were not explained in a good way. Like the lectures on Amortized analysis were not much effective, according to me.

Course has a slow pace by the time it reaches hashing and the videos only reads out the formulas.

The programming exercises are not friendly at all for learners new to python and algorithms.
