About the 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 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.

the last lecture was too fast. Would be good to divide this into two parts. Rest all is great stuff.

This is really good for beginners. This will explain you from basics to advance level uses of DS.

We need some feedback sometimes. It is way too hard to solve a question without error feed back.

The module on dynamic arrays was not well organized or explained, but otherwise a great course.

Very good insights in the data structures. There can be more focus on linked List, Graphs etc.

Overall a good course. In my opinion the hash-tables and BSTs material was a little rushed.

needs more illustrative videos for presenting the powerful applications of data structures

Good course. I personally think stress test code should be included with the starter code.

Good course, but the problem set is too small. They will be much better if they are more.

The optional videos are not allotted enough time. Those concepts are difficult to grasp.

First take an audit if teaching style suits you then only go for full course.
