Excellent course. Great coverage of data structures. Good practice questions and explanatory videos.

Good Course for Knowledge

It was difficult in using of pseudocode in my code

Great course

Algorithms in lectures were useless to programming assignment

The fact that test cases are not available is extremely frustrating and time consuming. I absolutely disagree with the instructors about the reason why test cases are hidden.

Hi,

Learning new complex things is time consuming, it is essential, and it is ok. Without this time spent you wouldn't have learned even half of what you've learned while trying to find your mistakes yourself. Also, the testing techniques presented here are indispensable in the real life, and many learners of the Algorithmic Toolbox course have already confirmed this

Hello Mr. Levin,

First please forgive me for communicating with you in this place. I am not sure if there is a direct way to answer you, but I believe you will have access to my response.

I entirely agree with what you said that this needs time and I do not mind spending time learning new things. That is why I am here in the first place. But I think that hiding the test sets misplaces the balance where this time is being spend.

Let me give you an example: week 3 – hash chains - assignment no. 2. I wrote the app, submitted this and it failed on test no. 5. Having generated tons of test cases I was nowhere closer as all looked good, but still failed your engine. As it turned out the problem was not with the algorithm implemented but with the presentation layer. ‘Check x’ command when x is not found in the hash table should return blank line and my program returned nothing. I could not find this in the specification hence lots of hours trying to figure out the solution.

It was not a bug with the program, it was the problem how the data is presented. I do not mind spending time developing solutions to the assignments. I would love if there were more advanced (even optional) problems to solve but I want to spend this time on the algorithm and solving the task rather than trying to figure out how to display the data.

Please, do not get me wrong, I absolutely adore the course, lectures are brilliant and my opinion should be regarded as a constructive criticism even if you do not agree with me. Thank you again for what you are doing.

Regards,

Marcin

An awesome course with real-world examples. Binary search trees lectures should be improved. They should have thought it with much detailed explanation. Anyways you will love this after doing assignments.

Great Course Highly Recommended.

There is hell lot of information to grasp. Must take this course. And put everything in it.

This course is very good for those who are trying to learn Data structure. well you have to have some basic knowledge of the programming languages like python, c++, java for the programming assignments.

Very good course for intermediate level. Thank you so much!

Effective course

Awesome

Great continuation of the Algorithmic toolbox course. There's a lot of new, interesting material here. The videos are very good, the slides are of high quality, and you will also find some good references to online university materials and interactive visualizations.

The homeworks are challenging but enjoyable, and you will also find some really challenging optional assignments here.

The only downside of the course is that unless your friends are computer scientists, you're going to lose them if you talk too much to them about AVL trees, distributed hash tables and splay trees! ☺

Even some programmers/coders scoff at these things, but as a programmer I'm certain that you will become a better at your job if you learn these.

Can't wait to start the next course in the specialization!

The course itself has amazing content as always. I've learned a lot.

It was very helpful.

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

Course was very good and it helped me a lot in developing my skills

pros: Very nice course, understandable materials, great instructors. I am very likely to recommand this course to my friends.

cons: The BST and AVL tree part seem to be a liittle unclear. The pseudocodes are not fully implemented.

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

Daniel M Kane !!! Super!!!

it's awesome course.

Lack of coding practice and didn't focus on the elaboration of Core Data structure. Better explanation will work.

It's become very useful to me, especially now I'm quite comfortable with algorithms and complexity.

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

very good

Good lecture format, good programming assignments. Strongly recommend
