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 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! Do you have technical problems? Write to us: coursera@hse.ru...

Data Structures was really interesting over all, also assignments are quite challenging. It's important to consult the external references & discussion forums if you want to get the best of it.

I found the course a little tough, but it's worth the effort. It takes more time than mentioned. Apart from that, it is actually good and covers most of the topics required for interviews.

All in all a great and challenging course. A big thank you to all the teachers! I especially liked the assignments as completing them forced me to think about all the little details and edge cases.

A few observations/constructive criticisms:

- While the first 3 weeks had almost everything explained rigorously, including complete, usable pseudo codes, the last 2 weeks had lots of holes in terms of details. I think it is down to the fact that it covered a lot, however, pseudo codes suddenly became very high level, to the point where a 5 liner translated to ~100 lines of real code. This in terms meant that learners had to do quite a bit of additional research about the nitty-gritty. Nevertheless I thoroughly enjoyed this extra research, just be mindful about the extra time required.

- There are languages with first class support, namely C++, Java and Python3, which means there are starter files supplied. If you choose a different, supported language then be prepared that you have to implement everything from scratch, which again mean extra time, although I would argue that you will learn more, especially in the last 2 weeks.

- Forums seemed to be more active in the past, especially with regards to teacher contribution. Be prepared to be self-reliant and able to come up with answers to your own questions.

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 .

Very good course for data structures like stack, queue, linked list, hash tables, binary search trees, splay trees, avl trees.

BST assignment has very challenging problems.

At first, I think the homework is really difficult. Since it seems like there's black box test.

But gradually I get accustomed to it.

I've learned a lot. And I can felt my growth clearly after conquering some difficulties.

Congratulations for this second course of the "Data Structures and Algorithms Specialization". This was again well-designed, informative, and most importantly an extremely educative course. Yes, it is demanding and some times requires significant effort and time for someone to pass the programming assignments. But there is "no free lunch"! Making easy to pass the tests or providing all the test cases may help more people to earn this certification, but the added value of a course that can really learn you how to design better algorithms will be missing. On the downside, I would ask from the instructors to further elaborate on some week lectures (modules), especially if the topic is going to be discussed in the corresponding programming assignments. The problem with the splay trees is probably characteristic. Overall, well done! Many thanks for the quality of the course you provide! Keep up the good work!

Even though this course requires completion of tough assignments, I believe that this gave me a chance to understand and grasp core concepts about data structure and also about programming skills.

Amazing course.

Interesting exercises help with learning and understanding of internal mechanisms basic data structures, how some of them work, the pros and cons of each.

Thanks!
