One of the best online classes I have ever had! That said, this is probably not a course for someone who don't know data structures already. I learned data structures and algorithms a couple years ago and had done many interview algorithm problems so this series of courses help me to review things I know in C++. Nevertheless, great course design, great material and incredible presentation by the instructor!

Excellent course! Looking forward to a more advanced course from the same course staff!

The lecturer is super excellent and super clear. I wish he has more courses here.

An outstanding conclusion to this MOOC specialization. I have learnt a huge amount on this course, and the opportunity to do programming assignments where you have to make additions to a provided substantial codebase is a brilliant learning strategy. The exposure to this high-quality code gives you plenty to read/digest. Meanwhile, the quizzes are superb and consolidate learning, and the video lectures are excellent. All in all, brilliant; you both learn a huge amount about computer science/data structures & algorithms, and you also develop some serious exposure to C++. Thoroughly recommend this Specialization.

Great (non-math proof) introduction to topics such as Disjoint sets and Graphs. It's a bit more theoretical than the other two courses and topics are covered at a high level with decent examples. Of the three courses, this one was more confusing and challenging at times. I'd definitely recommend this course as a good foundational stepping stone to other algorithm specializations on Coursera.

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.

Very Challenging course. Learned a lot, very clear instruction. Assignments were interesting and challenging.

Simple examples make the concepts easy to understand. A great course.

Thanks for offering this challenging course!

Great class! Exceeded my expectations!

One of the best courses in Coursera!

Good course with good exercises.

Great Assignments...

Awesome!

Great course! Very interesting lecture material / content. I can't give this course a five however, as the assignments seem unnecessarily convoluted, and abstracted to demonstrate the material.

I wish the course was more detailed. Some PDFs to explain the concept more. Other than that I am happy with the content.

This course is good though some of the contents may need refinement. Code examples are very helpful.

Very Nice Course, recommended for every Computer student.

I've audited this course. It was useful for me. Thanks.

Needs to be a bit more in detail

Quick, automatic grading is nice, but final challenge problems that require simply filling in a couple of lines, and not enough problems requiring one to write a function on one's own.
