About this course

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!

great course with challenging assignments, the problem with the course is the accent of some of the lecturers which make the lecture harder to follow also not enough examples in the lectures

Course is very knowledgeable and is deigned properly but the allocated time for assignments is too less than the time specified. Also some assignments need more support in the forum

This is one of the appreciable course for the learners. The lectures and the reading material were great and the assignments was challenging. Overall this is a very good platform to learn.

The best data structures course that I have taken! The complex topics are made simpler at the expense of teaching style that allowed me to make it applicable in a real world situations.

It is a very helpful course to help you get started with coding. It helped me write neater code and helped me think on a problem without giving up. I also plan to increase my grade in the course.

Everything is great except week 6. One of the video has mistakes in its subtitles and the lecturer in this week don't make me feel comfortable to listen to him. His voice is bad!

Excellent review on data structures. I've taken a graduate level course covering advanced data structures, but I was still able to learn new things through the challenging assignments.

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.

The assignments were really challenging and fun to do. I hope there will be more courses like from you. I also like teaching style. There should be more number of questions in quiz.

In depth mathematical analysis and implementation of important Data Structures. This is a very good course for programmers looking to solve computational problems with first principles.

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 guess it's the best course in this specialization. It will introduce to different data structures and their application. For those who are new to computer science, it's an enlightening course.
