This is a great class. I learned / re-learned a ton. The assignments were challenge and left a definite feel of accomplishment. The programming environment and automated grading system were excellent.

This course tells the basic algorithms and data structures, the best place of this course is the high quality of its assignments. They not only strengthened the understanding of the algorithm, and made us konw the importance of paying special attention to the exception handling, processing, immutable data types, function calls with no side effects, time complexity and space complexity, and these assignmnets help us to think about any possible corner cases, deepened our coding ability or is benefit for future programming work.

Amazing course! Loved the video lectures, the material is tough but the logic of lectures and the course itself is very clear. Also there is a book where you can find more details. I also loved the assignments, they were tough as well but very interesting. Don't afraid if it is your first experience in Java, if you know the basics you can pass them (also there is real help in forums). So I recommend this course for everybody who wants to learn some practical applications of algorithms and to know the basic theory. Thank you!

I really like this course. I think the pace of video is appropriate, clearly explaining the main knowledge of each part but not digging into details too much. for me,

I never learned algorithm or java before, but I can mostly grab the lecture content. Another reason I like about the course is the amazing programming assignment part. Each assignment is a little bit challenging but not overwhelming and you can exactly know how well you did through the precisely computing grader system. Thanks for such a wonderful CS course!

Very well structured course. Amazing booksite and the full book with a bunch of practical exercises available. Lectures do not simply repeat what you can read in the book but concentrate on the gist and give advanced explanations and live demos of the most important concepts.

Programming assignments are designed in very capturing manner. I was challenged to solve interesting practical task meanwhile algorithm itself was only a tool to do it. And very detailed auto-grading tests ensured me that I used that tool correctly.

Fantastic hands-on course that helps you explore algorithms. You should be pretty comfortable with programming in Java (comfortable with creating linked data structures) to get the most of out of it.

Assignments are incredibly well designed and allow you to make progress without much instructor. The discussion board is pretty responsive from other students in the course.

A great supplement if you have taken/are taking an algorithm course without any programming assignments (or poorly structured programming assignments)

Great course for two reasons: 1) if you look at the reference code in the slides and extended materials, you will be amazed at how simple (and elegant) the implementations are. It's definitely a good point every serious programmer should strive for; 2) Each programming assignment were designed very very carefully. If you download the project zip files, you will see ton of testing datasets for debugging. Apparently they (the test data) had been chosen to help correct your solution, which are often very hard to obtain.

This is an excellent course. The video lectures are well made and highly informative, explaining the theory behind each algorithm, demonstrating the algorithm in action, and providing snippets of code for implementation. The assignments are quite challenging, especially if you're new to Java like me, but with some effort they are doable. Just be patient, read the output from the autograder, and don't be afraid to seek help on the forums. This course wil absolutely make you a better programmer and computer scientist.

Just by completing this course, doesn't mean now you know "Algorithms" you have to keep on revising and the content in this course is really deep for which you have to come back again to this course just to fulfill your thirst to understand algorithms. In my opinion this course is really great and the assignments are also kind of brain twisters, by which you will learn a lot not just about algorithms but about the language in which you are writing your code in this case it is Java. 5 stars from me to this course

This course is a really good intermediate-level course. The course content is really good and interesting. It covers all the points which are necessary to study algorithms. I particularly found the assignments most interesting and challenging. The most interesting was the autograder. It tested each and every case and deducted the points if any case failed. So to score full, one has to work really hard.

I thank the instructors for this wonderful course and also to the mentors who actively supported on the forums.

I wanted to refresh my algorithms to get ready for more challenging work. This course is awesome! It gave me a head-start to start tackling programming problems.

I am grateful to the instructors to make such a course available for people like me who are not only physically far but also have less time each week due to full time work commitments. I am glad I took this course and diligently attempted the assignments. Courses like these makes me a better programmer. Next, I am headed to Algorithms-II. Cheers!

The course is absolutely awesome! A lot of practical information about methods and about general thinking approaches that are essential for anyone who has to write efficient code for solving various problems.

I also want to highlight the very high quality slides and presentations, it is clear that the creators of the course made a lot of effort in it.

Finally, I really liked the programming assignments and the way they gave feedback about the correctness of them!

Thank you very much for your work!

3 month later, i'am come back, and finally complete this well-known course.

If you just familiar with java, i strongly recommend you don't enroll this course, accomplish at least 80 problems in Leetcode before take the course, the explore -> learn -> tree category helps me understood recursion.

This course is a big challenge to me, but when i finish it, i not only learnt algorithm knowledge, but also debugging skills.(I understand why some people use "println" instead of "breakpoint")

Thank you...

The course is easy to understand and its prerequisite is acceptable to high school students. Thanks to R.Sedgewick and other authors.Though English is not my first language, but the course formulated the algorithms and data structures by a comprehensive way that could be learnt by a people without much exps. BTW, the programming assignments have a complex online grader, finishing those assignments will greatly develop your ability of applying algorithms and debugging as well.

Thorough introduction to the study and application of Algorithms. Assignments are challenging yet achievable. Entertaining and informative lectures.

For those considering taking the course; I had no previous experience with Java, and only high-school level Math (barely). You can get through. You may better appreciate some of the material with more Mathematical maturity, but it isn't absolutely necessary - don't let the maths discourage you, pick it up as you need it.

Fantastic course. Great in-depth discussion of various algorithms, and the hands-on approach to implementation is a welcome change from pure theory classes (although you get plenty of that, too). The programming assignments were a real eye-opener as to the power of carefully designed algorithms.

The full potential of the course is best realized with the accompanying textbook and the huge amount of material available on the booksite (which is free).

I simply loved this course a lot. I tried to start and finish this atleast 5 times previously, but never was I able to go past 3-4th video. But then I decided to do it one time by whatever means possible. And when I did finish it, I started to love Data Structures and Algorithms. I am now having some knowledge about how we use DS n Algos to solve some of the most trivial problems. Thanks a lot to the creator of this course, You are a GOD to me.

For a non-English speaker, the professor introduced and analyzed details and design soul of each algorithm in a simple but accurate way. If 10% of my country's university can treat education in such a delicate attitude, great willings of a crowd of ambitious students would not be failed, I think.

In addition, the assignment is instructive and well-designed, which benefited me a lot whenever I was trying to work it out or after finished it.

A great introduction to fundamental algorithms. This course is very well thought-out, the instructor always makes his points very clearly an convincingly: more than just algorithms, this course transmits a way of thinking about them. The material is very well polished, you can feel the instructor has been teaching this topic for so many years. In addition to all of this, the programming assignments' topic are generally quite exciting.

This course gives a very good overview of algorithms, justifying each new data structure or technique by examining the performance and technical problems that it is trying to solve, and explaining the meaning of the approach. It is a good idea to do a good bit of coding on your own, however, as the Assignments typically expect you to USE the data structures explained in the lectures from a static library rather than hand-coded.

I've not merely learnt lots of practical methods to solve the specific algorithm problems within this course, moreover, I've been able to manage to cope with other else algorithm problems, cuz, this course has taught me the through and thinking of using algorithm to solve a problem, including to understand an algorithm, and use it, and eventually get a solution to any specific problem.

Thanks to Professor Robert Sedgewicks

Recommend print the ppt then listen to the lecture cuz that would save your time. These homework impresses me deeply, and I did spend a lot of time completing them. Fortunately, I got a not-bad accomplishment at this class. I think everyone would like to have a solid foundation on algorithm as long as s/he study hard in this class. Thanks a lot for providing such a great open class! I love you professors! I love princeton!

I took this course to refresh my Data Structures and Algorithms knowledge in order to prepare for technical interviews, and I'm glad I did. The lectures are great and the programming assignments are very well designed and have sufficient guidance. You really have to work on them. I would have liked more graded MCQs after lectures. This is also the first MOOC I've completed, and it gives me a great sense of accomplishment!

Very interesting, I finally started to study seriously and learnt a lot, by using the correct Data Structures (and also learning them), learning sorts, I enjoyed a lot, and found very interesting exercises, I learnt the definition of Binary Heap, how better implement the Priority Queue Data Structure, Binary trees, and very fascinating the way Red Black Tree is implemented, and the technique used to maintain it balanced

The grading system is very helpful for debugging

A little suggestion, personally i would not go to the forum unless i meet problems, but actually i find i may missed some great thinking for ignoring it. It would be better if there is a subscription feature like what's trending on the Forum to reminder learners to participate in the discussion.

And i like the every week's interview question, thank you for all your effort!

A very interesting course, very well taught. The course is carried out in a very methodological way, builds the knowledge gradually step by step. The course is suitable both for those who know the material and want to refresh their knowledge and for those who learn this for the first time.

Finally, I would like to say that it was a privilege as much as it was enjoyable to learn from the great Prof. Robert Sedgewick !
