About the Course

This course covers the essential information that every serious programmer needs to know about algorithms and data structures, with emphasis on applications and scientific performance analysis of Java implementations. Part I covers elementary data structures, sorting, and searching algorithms. Part II focuses on graph- and string-processing algorithms. All the features of this course are available for free. People who are interested in digging deeper into the content may wish to obtain the textbook Algorithms, Fourth Edition (upon which the course is based) or visit the website algs4.cs.princeton.edu for a wealth of additional material. This course does not offer a certificate upon completion....

If you want to learn and explore more challenging parts of Algorithms, you should definitely learn this course. The experience and knowledge of the teacher is pretty obvious from the way he teaches.

Really helpful in understanding concepts in algorithms and data structures.I would suggest if another course with similar quality has been made available for students who wish to learn Java course.

This course is very helpful with me. It helps me review a lot of materials about algorithms I've learn from my university. Thanks professors and other members for a great course. If you want to solid your knowledge, don't hesitate to take this course, it's total worth it.

The course was really good in giving real time examples of the algorithms and its usability in the real world ,the course should also have offered few more assignment covering each topic in the assignments using every component of the course!

Excellent Course. Very Good Assignments and the Autograding feature.

Some of the topics are difficult to understand. So, I think their explanation should be as per level so that all the students can understand instead of moving forward.

I took this course to get a taste of Coursera courses and a refresher on my algorithm. The course is very informational and clear (Robert is a great professor) but the home assignments are much more challenging than the course material

Great course. Sedgewick has good educational skills. The course also contains good examples and interesting assignments. I struggled a bit with the first assignments, but then I liked the last 2 better. Looking forward to part 2.

Excellent course. Good lectures and interesting and challenging problems. Only drawback is that we are forced to use Java. It obviously helps with grading, but would have liked to use a language I am more familiar with.

One of the best algorithm courses available online. The hands on assignments will ensure that the concepts are clearly understood to be able to solve them. The community discussion and the course materials are amazing

Make sure you look at the FAQ for the assignment specification! It's easy to miss (when reading in the specification, look at the top right corner) and would have saved me a lot of headache on some of the assignments.

Material seems good, reasonably interesting and can be challenging. - I would appreciate more graded assignments, solutions for the interview problems - In my opinion spends too much time on details of Java

Java is a poor choice as a coding language for this course . The problem with the generic arrays is unbearable. I strongly recommend to migrate this course to C# or to accept C# for coding assignments.

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.

I think it is a good course. I have known more about time complexity of algorithms and some applications of different kinds of the algorithms. I have spent more time then I though for this course.

It is really good course. However for me, I took more time than the specified to solve the problems. I needed to do some research in the forums, because the instructions were not clear sometimes.

The course lost a lot without tests. Theory is great. Assignments are pain in the azz - too much is assumed here and there. You must resubmit like a dozen of times to figure out what is wrong.

The lectures were easy to understand and the teacher did a good job explaining the material, however the assignments were a little vague and it was hard to understand exactly how to do them.

This was a very informative and elaborative course on algorithms . It helped me a lot in upskilling . I will try to revise the concepts as it have helped me a lot during the sessions .

Really good course to learn fundamental knowledge on algorithm. Programming assignment is very useful. However, lots of details of algorithm are not covered due to time constraint

content is great but the discussion forum is a little sparse, some of the assignments are significantly more challenging than others but the course was very rewarding to complete

The course is awesome. It's absolutely for beginners. If it had been in C++, it would be better and more interesting. Professors are awesome. I haven't seen any course like this.

The course is very difficult, but the quality is excellent. Due to the stringent grading of the program submissions, I believe more help should offered for each assignment.

This is the hardest course I've ever taken. If it were not this hard, I'd give it 5 stars.But I do have learned a lot. Now I'm on my way to build kdtree instead of 2dtree.

Very nice training, I enjoyed mostly the applications of them by implementing the programming assignments. What is missing is a training certification though.

Overall, very good course. The only thing keeping this from being a 5-star course is the lack of resources around comparing completed programming assignments.

This course is very useful, the assignments are challenging. The autograder is well prepared and very helpful on improving my implementation of algorithms.

The Explanation is good and in depth.Just please write Java Code in the new standard i.e. like using System.out.println(...) instead of StdOut or StdIn
