The course provides a broad overview of essential data structures and algorithms in an easily comprehensible manner and without delving too much into mathematical proofs. However, despite the good lectures and an elegant, concisely-written accompanying Java library that implements almost all the demonstrated algorithms in the course, learners would benefit much more if the programming assignments are easier, or the assignments are provided with more guidance. This is because these assignments seem specifically designed for university students and not Coursera learners, and indeed in the official course taught at Princeton, some of the same assignments even require working with a partner. Furthermore, the course seems to take a passive approach in developing learners' understanding of its algorithms by providing the written code (again, very concise and easy to understand) and learners peek behind the code instead of implementing it themselves; this may work well for an introductory course, but does not solidify some tricky concepts as well as requiring students for implementations based on the lectures and slides.

Everything was great in this course, only complaint was the collinear points assignment. For some reason, the auto-grader was messing up and you had to have the LineSegment.java file in the zip file, but if you did it normally with or without the LineSegment.java file in the zip you will get a 0, since the auto-grader will complain. There was no mentor that helped with the problem (There was another thread that has since been deleted). It was only until another user mentioned putting everything in LineSegment after the BruteCollinearPoints and FastCollinearPoints. However, this approach is generally not a good practice since you now have two outer classes in two different files, and the class LineSegment is the same in both. It also means that you will always lose 5% due to style checks, since we are forced to put the class of LineSegment into each java files (Brute and Fast). Not sure why the auto-gradered needed LineSegment.java when it wasn't part of the requirement. For these reasons, I deducted 2 stars.

As someone who works full time, this course assigns too much work for per week. In addition, instructions for assignments are not clear enough and the link between assignments and lecture content is often not pointed out clearly.

they must take assignments are compatible to other language also but not only java

because it is not a language course it is a dsa course

The topics are discussed in kind of a too broad and generic way. Some lectures are great others are a bit dry.
