About the Course

The Unordered Data Structures course covers the data structures and algorithms needed to implement hash tables, disjoint sets and graphs. These fundamental data structures are useful for unordered data. For example, a hash table provides immediate access to data indexed by an arbitrary key value, that could be a number (such as a memory address for cached memory), a URL (such as for a web cache) or a dictionary. Graphs are used to represent relationships between items, and this course covers several different data structures for representing graphs and several different algorithms for traversing graphs, including finding the shortest route from one node to another node. These graph algorithms will also depend on another concept called disjoint sets, so this course will also cover its data structure and associated algorithms....

Great Teacher, although there are still a lot that I need to learn on my own(I come from non-CS background), after hereing these lectures, I feel that I have already learnt a ton.

This course had good coverage on hashing, disjoint sets, graphs. This course will improve coding skills.

I'm happy with material, coding practices, quiz and projects.

This looks like a compressed course and it is, but the beauty of this course is that it covers all the topics so well that you don't need to go through anything else. Yes, it would help if you have a background in programming and some idea about data structures.

Especially after looking into other, similar coursera and/or online courses, I have to say that the course quality and teaching quality of this course and the other two courses, is by far the best. Thanks, it was a lot of fun & I learned a lot!

The third course in the specialization was quite dense, but the instructor did a great job providing a sufficiently clear overview + detail; the assignments are fun and interesting. Would be good to have more opportunities to code.

Great introduction to Unordered Data Structures, a topic I was unfamiliar with. This class is a little more challenging then the first two classes in the sequence but well worth the additional C++ experience and information.

The course has amazing explanations of data structures and thoughtful exercises. If I had one gripe it would be that there is too little coding. While the exercises require thinking you don't write a whole lot of code.

The course contains enough assignments and projects to strengthen what we're taught on class. Also, the two projects are really challenging. I was filled with enormous satisfaction when I passed 100% of them.

Fantastic teacher and great material !!

Thank you again for sharing your enthusiasm in such an efficient format for a quick tour on the study of ADT. Only wishing you'd make more content on Coursera !

It was a quick yet detailed intro to unordered data structures. A bit more advanced or difficult but very interesting. Enjoyed a lot.
