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....

Incredible learning experience. Every programmer in industry should take this course if only to dispel the idea that with the advent of cloud computing exponential algorithms can still ruin your day!

Extremely well designed course. The assignments touch all the concepts taught in the class. Lot of concepts get clarified when you try to reach 100% on each assignment. Highly recommend this course.

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.

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

Good lectures, challenging assignments. Though the explanation of the assignments are very hard to understand, need to work on it to make it simple.

Great course, it really paved a way for me on how to think about Algorithms! Respect for the instructors for bringing such a quality course.

Lectures and content are good. Was probably better on the old coursera platform, since a lot of the exercises have never been migrated over.

Challenging assignments, great code example from book site. However, the way the author delivers speech is not really easy to understand.

Would be beneficial to spend more time building intuition though I understand how difficult it must be to balance depth and time spent.

its a great course, but, unfortunatelly not all exercises all graded and are important ones.

Anyway, I recommend this course to everyone

Great and challenging course. The environmental setup could be better and some some of the project descriptions could be more clear.

Great course! The assignments were challenging but not so hard that it made my brain melt. tons of great info on runtime analysis
