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.

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.

Less diagramatic explaination.....making it hard for some concepts to grab.....overall good

This is a great course which gives you the basic understanding required in handling data structures along with some state of the art techniques and applications for those structures. Had a little difficulty in following binary search trees because of the pace of the course and lacking detailed explanation at places. But overall it is a really good course to get up to speed on some of the most used Data Structures.

This course is very useful for programmers and contains in depth detail of the various commonly used data structures.

Binary search trees were not explained very well. Programming assignments are usually very easy. Nevertheless, it is a very interesting course and the assignment do help to learn about the topics covered. Useful.

Few more data structures can be included like Graphs .

The assignment should provide more problems related to BST and other trees.

Even though I am already aware of all these data structures, I gained some more in-depth knowledge about them, also got introduced to splay trees. definitely worth a try,some of the assignments are really good.

More exercise will be better. It will be good you mention red-black tree segment and interval trees B and B+ trees

The quality of the course is very high. However I give a slightly lower rating than for the Class 1 from the specialization. The assignments seemed little unbalanced this time - some were very easy while other were very hard (I passed one after loading a special package to manipulate data or recursion limit).

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

Great course! I figured disjoint sets was pretty interesting - the rest of the material I get by with no issues, but boy: the BST advanced assignments (splay trees) in week 6 is by far the hardest assignments I tried in both Algorithmic Toolbox and Data Structures. It's a pretty big jump in difficulty (I don't think they explained splay trees in the lectures very well; it was pretty fast), but I was so ecstatic when I solved it that I didn't mind.

This is a very good course. The only thing I had problems with was the way the tests were set up - they were giving me no information about why my code was failing. I understand the reasoning behind not releasing test cases in failing tests, but like me - a lot of people keep submitting and failing, and in the end getting discouraged . Suggesting modification of test case outputs in the future.

Excellent course in general, and I learned a lot of new data structures that one doesn't generally learn about in standard algorithms and data structures courses, like disjoint sets and splay trees.
Only complaint is that sometimes the problems are too complicated for how easy they are. By this I mean that the problem statement is very long and elaborate, when what they are really asking is something trivial that can be programmed in a few lines, but it takes a while to understand just what they are asking.

I've learnt a lot. The content is very interesting but a bit challenging. I had hard times accomplishing all the assignment and put much more work than I expected.

The final module with the Splay tree is way too difficult when compared to the rest of the material in the course. This course would be better structured with three assignments as follows: 1) tree order problem, 2) a simpler tree assignment that only deals with a basic binary search tree, 3) the set range sum problem implementing the splay tree, as an advanced problem. Aside from the difficulty of the last module, this is a great course. It's very comprehensive and you'll take away lots of useful information on course completion.

Overall the course is good. The last two weeks on AVL and
Splay trees need more examples and felt a bit rushed.

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