## О курсе

The primary topics in this part of the specialization are: data structures (heaps, balanced search trees, hash tables, bloom filters), graph primitives (applications of breadth-first and depth-first search, connectivity, shortest paths), and their applications (ranging from deduplication to social network analysis)....

Awesome course! Professor Roughgarden is fantastic. The material was appropriately challenging. Perfect amount of rigor. Only one minor squabble: the hash problem set is terribly misleading.

It was an awesome experience to learn from such a teacher. Now I have a much clear view of the graph algorithms. I have enjoyed this course. Thanks to Stanford for offering this course.

The only reason this is not a 5-star review is because of the Week 4 programming assignment. The point of Week 4 is to demonstrate the usefulness of using a hash table when frequent look-ups are necessary. However, the constants inherent to the assignment problem make the suggested algorithm take anywhere from 30 min to hours. Meanwhile, there is another algorithm that can accomplish the task in mere seconds, but this is not apparent without scouring the message boards for help. I feel it would be better to either rethink the assignment to bring it more in line with the point of the teaching material, or deliver some instruction on the actually useful algorithm, which is fascinating in its own right.

Otherwise, this course is excellent as usual.

Great course for computer scientists. It is easy to understand but it takes too much time to be completed. The video lectures were long and full of too much explanation. And the week 4 programming assignment took very long running time to complete using the algorithm specified in the course but less time using other algorithms.

Great course; especially on Data Structures and when certain ones are appropriate. I do wish the final exam solutions would be posted after completing the exam successfully in the same way the problem set solutions, hints and comments are provided.

the later graph algorithms are implemented rather cursory. It is quite hard for us to implement it at home using a "big idea" as given in the video. I wish the instructor could give us some intuitions of how Java, C++, or Python handle the case.

Great course but needs restructuring. The videos of how an algorithm works come after extensive discussion on what its action's running times are. If this were flipped and we learned how it works before running times it would be more intuitive.

Great course! The programming assignment for Week 4 was a bit demoralizing, though. I am very certain I had the right answer, but had to implement another solution that did not involve Hash Tables in order for it to process in < 24 hours.

Great course, the first exercise was a little bit hard but the material is useful, if you read the relevant book then the course is even easier.

Last I want to mention that writing the code in Python makes the course easier.

The material was a little light and far fewer video quiz questions to test our understanding of the material. I also tried to test myself on BFS and DFS by doing online quizzes like geeksforgeeks - bombed really hard.

assignments didn't seem as interesting or complex as class 1, besides week 1 of class 2. Lecture material was high quality however, and the advanced optional material is appreciated

Hope the professor could teach more about hashing and give a detailed implementation of some data structures or supply some interface template code.

This course was much harder than the first one. Plan to spend extra time doing the assignments. However, it is totally worth it!

Great course! Best one for refreshing concepts! Can act as a starting point too! Absolutely love the explanation.
