Excellent for working on string related problems in competetive coding as well as development profiles.

Relatively hard course! The problem sets were extremely good. Ensures putting enough effort and time.

Good course that teaches Burrows wheeler transform, KMP algorithm. The assignments are also very good.

I would be interesting update Algorihm on Strings to construction of suffix arrays in linear time.

I would recommend this part to anyone who wants to learn string algorithms. Thanks for the course!

Mil gracias National Research University Higher School of Economics, mil gracias Coursera.

Very nice course, the toughest one up until now in the specialization. But a rewarding one

Great Course, assignment a little bit harder than previous courses in the specialization

Awesome explanations and challenging problems like in all previous courses! Thank you!

Course is really tough, but I'm glad by the information I have got from this course!

Interesting topics; especially useful to people with an interest on bioinformatics.

Give very good knowledge for string process tools, and related common algorithms.

Very hard course, if not the most hardest course in the specialization. Try it!

The forum was empty when taking class. Might be because this class expired

Difficulty level increased a bit compared to first 3 courses, be prepared!

Very Challenging! Assignments are great to learn the algorithms deeply.

Very good course on efficient algorithms for processing long sequences.

This is very nice course and I learned various things in this course.

This is an interesting and useful but a bit difficult course.

Excellent course, properly designed and well presented...

An amazing course it cover a lot of content in few weeks

It is difficult, but it is great especially the videos.

This course help me to mastery on string algorithms.

I really loved this course and it was so use full

thank you, course was good, highly recommended.
