The best online course I've taken so far. The autograder really does its job! The tests are so thorough that it always takes me several attempts to finish an assignment, but it is always worth it!

The course focuses on Java specific implementations of algorithms, so if you're not from a Java background, you would have a little difficulty with the assignments.The course content however is great.

A great introduction to data structures and algorithms. I feel like I have a much better understanding of algorithms, and what goes into their development. Keep in mind, there is a lot of information to take in...try your best to complete the optional exercises, and participate in the discussion boards. You will gain much more by doing this.

This course contains the best lectures I've ever had about algorithms. Robert Sedgewick makes it really easy to understand the algorithms he is talking about and he doesn't limit the topics to basic entry level.The assignments were challenging but doable. For sure I learned a lot from this course. I would rate it 6 stars if it was possible.

Exceptionally good. I am a working professional with 13+ years of development experience and still found this course to be full of high value and knowledge. I really never looked at these algorithms the way it is represented in this course. I am very thankful to Coursera and Princeton University for making this course available to everyone.

Wow. I can’t believe I completed this course. Assignments were so tough. Wonderful course structure, lectures and handouts. I can’t explain how much I loved challenging assignments. It’s going to straight away impact my day to day work. “You don’t need a super computer, you need an efficient algorithms”. Well said. Excited to start part 2.

Very solid course, at a perfect level for students with fundamental Comp-Sci skills who haven't coded in Java for a while and need a refresher on both Java and basic data structures and algorithms. Videos actually contribute to learning and assignments are challenging but not overly difficult and there's a lot of support online.

Thank you!

I want to say thanks to creators of this course. Explanations very clear, awesome presentations and demos. Also I want to highlight assignments and amazing auto-grader, which with extreme accuracy examine your solution. This is awesome course and I'm really happy that I finished it. It was not easy, but very useful. See you in Part 2 :)

I had passed out of college 4 years to this day , and have taken few Algorithms courses. Never before I have been able to understand and implement Data-structures and algorithms to such an extend before. Recommend this course to everyone who has some basic knowledge of java/programming and want's to start understanding Algorithms.

Honestly this course requires a lot of concentrated efforts and is surely a brain twister.

I learned quiet a lot in terms of applications of DS and algorithms to real world problems.

Thank you to Coursera, faculty members and supporting staff for bringing in such a in-depth course free of cost to the interested students.

Best Regards

I thoroughly enjoyed the course! The lecture videos and slides are great in explaining the fundamentals, while the assignments are challenging and rewarding (Also, thanks for all those helpful pointers in the assignment checklists). I especially liked the practical examples, and "enrichment" sections. Looking forward to Part II

Well explained and very interesting (also because of all the examples of applications done in the course that can make you think not only of "how" but also of "why" algorithms are developed).

Assignment are very helpful in learning how a data structure or an algorithm behave the hard way!

I surely recommend this to my colleagues!

I really like this course. It is a good recap of algorithms which I learned in my masters. Reasons for going to further approach and examples are given good. I feel if more real time examples are provided it will be good for students to understand where they can apply these algorithms or they can implement their own algorithms.

Super course! I love all the assignments. and the upload-and-feedback system. The lectures are also very good. I did not use the interview questions.

Getting the course done in time and working full time simultaneously is very hard, though, but I don't really have any programming experience with me, so that might make it harder.

A great course.

I refreshed my knowledge of data structures and learned lot of things about Java, language that before this course I never ever use. However there is a little negative note, I would have preferred that inside the project file will be test files. For reach full test correcteness i did every time a treasure hunt.

Probably one of the best courses on this whole website. The prof and accompanying textbook and website are clear and fairly concise. The assignments are challenging but fair and the autograder works really well so you get instant feedback.

Probably the only con is having to setup up Java on your computer which can be a pain,

Absolutely exceptional class. Lectures are clear as a bell, and the assignments are calibrated at just the right level of difficulty. If I have any nit to pick, it's that the required assignment APIs can be obscure at times (you really get into the weeds with having to, say, return an interface), but that's a minor point.

this is the best course in terms of algorithm and data structure point of view. i am totally satisfy from this course. it makes my thinking more broad and certain so i'm able to coreleate programming world to the real world problems. in my opinion it is best course for a person who possess some knowledge about programming.

Strongly recommended!

This course clearly introduces the basic algorithms and data structures to the students. The professor not only explains the concept of the algorithms but also shows us the applications of them. The homework of this course is substantial and deep. It is really worthwhile to spend time on the homework.

Talvez seja o melhor curso de algoritmos disponível na internet. As aulas teóricas são ministradas de forma profunda e completa por um dos mais renomados pesquisadores e desenvolvedores da área. Os exercícios práticos são desafiadores (no melhor sentido da palavra) e contribuem muito para o aprendizado dos assuntos.

Very good explanation with programming assignments that are of "appropriate" difficulty - not too difficult but definitely make you think. The instructors and the mentors have done an AWESOME job with the automatic evaluation the submitted code to provide detailed feedback. Loved it and will sign up for Part II now!

Rigorous but worth it. Take this course if you want in-depth explanations of many classic fundamental data structures and algorithms. The assignments take many hours a piece and require a sound knowledge of Java, but they will help you understand applications of the fundamental data structures covered in the course.

Great topics covered! They are all clear and straightforward. This course makes topics that have been obscured to me during college wayyy easier to understand. Professor Sedgewick's lectures make topics like Red Black Tree a piece of cake. I highly recommend this course. It is well worth every minute spent.

Exceptional course overall.

Only concern might be the lack of mathematical rigor which is more typical of algorithmic courses, but that might not be particularly important.

Provides an excellent set of exercises and programming challenges to really explore the value, design, and utilization of powerful algorithms.

Best Course that one can take to sharpen his skills. Very thanks to Robert Sedgewick and Kevin Wayne for coming up with this course. Before taking this course I used to think I have reached an end to my goal of learning Computer Science but now I feel the boat I was sailing was taking me in the wrong direction.

I really enjoyed participating in this course. Assignments may be sometimes tough, sometimes mindbending but they surely doable. Indeed I had a great time writing and debugging these programs.

Big thanks to Bob Sedgewick for great lectures! I think I gonna buy Algorimths book to express my gratitude to authors!

I love the way the course content builds up. There is a very intuitive flow to the each week's content. We start with a very basic data structure and the problem we are trying to solve. Then we point out short comings of this data structure. Then we iterate on it to improve. Its really easy to follow this way.
