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.

The lectures and the reading material were great. The assignments are challenging and require thought before attempting. The forums were really useful when I got stuck with the assignments

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

The course is great. However, I think there should be more stuff and practice about trees. The current videos and assignments are not enough to cover it.

Learn a lot from this. The last week gets hard but its as rewarding as challenging.

This course gives you real world examples of the data structures that you are going to learn and implement and and this really helps in answering the basic question "Why am I doing for what am I doing?". The programming questions are challenging and solving it actually helps you understand every aspect of the data structure that you are applying to the question.

Overall this course has improved my understanding of data structures and also where to apply it.Wonderful work by the instructors!

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.

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!
