Its a very good course overall. Just felt that towards the end the material got too much to digest, might be a good idea to split the contents of weeks 3 and 4 into 3 or 4 weeks.

I have only one feedback: the relation between subsequent weeks are not clear. It feels like I am learning one technique in week 3, and then another in week 4, but why is the technique in week 4 necessary? What are the differences in terms of functionality, between the various techniques? I think these points are not explained quite clearly.

Great course though, thank you very much!

Course Content is good. Instructors are not that much active to give answers for the raised questions compared to earlier courses.

The programming assignment should be more clean with detailed instruction in each code file.

Still stuck at Problem 5 of Week 1, had to left this problem undone.

Wondering if the mentors or professors can send those who completed the course the standard/reference solution/program via Email???

The lectures are a little bit confused

It would be nice if you could deliver the problem's solutions after the course ended. I ran out of ideas for the BetterBWMatching problem and i couldn't overcome the time issues.

A good course giving insight into how important string algorithms are for not only to computer science community but also its use in other disciplines like bioinformatics etc.

too complex, and I don't think in the future work I will apply these.

Quite an interesting and well-organised course, giving a detailed overview of the pattern matching problem and solutions for it (on the other hand, if you are expecting to see a wide variety of string problems, the course title is misleading).

Assignments and quizes are also likeable (although the pseudocodes in the slides and the code skeletons for the solutions contain quite a number of mistakes).

Overall, I shall give the course 5 stars, however, I am not very satisfied with the first two weeks. The slides are incomplete and listening to the video is a headache. The professor just confused me and I cannot follow since the material is not well taught. The first week's assignment is so difficult and it spends me several days instead of declared three hours (although almost none of assignments could be done in three hours). The 2nd weeks however, the assignment is so simple. But the most annoying part is still the way it is taught in the first two weeks which almost make me quit this course.

Some tasks was hard to understand and solve, but it in general it was good.

Very Good

Spent a lot of time trying to solve the last advanced task in the last assignment, but never solved it. I'm not sure if there is a mistake in slides or my misunderstanding, but it was really hard. Thanks to all the instructors.

very good and useful , but the last week algorithm is very complicated

Está perro

I have finished the specialization. This course is mostly useful though challenging.

necessary experience

The lectures are excellent. However, with reference to the logistics, it would really make sense provide test cases that are run. At least, the test cases should be made available once the student completes the assignment. By looking at the test cases, students can understand better with reference to developing better test cases in the future.

The explanation is very clear

Great course with great content.

However the video explanations could be better. It is hard to truly understand the concept through the videos. I just watched the videos to serve as a "roadmap" and to really understand the topics you'd have to read the chapters from the books listed in their reading section.

Still a good course overall and homework assignments are great.

I think last week was too complex and not that exciting.

Very difficult test programs

The lecture was very abstract and difficult. I could pass the course somehow by writing the code presented in the lecture, but I must say I understand less than the half of the course contents.

###

Responding to question from the instructor, I clarify the comments above.

I found the whole lecture difficult. This may be because the subject is not something I have even thought about. It was difficult to understand the difference and importance of key concepts such as trie, suffix, class, etc. Overall, I learned that the tricks somehow work, but my comprehension was not as deep as I can think about the extension or applications. I guess more examples or providing intuition would help me to digest the material.
