关于此课程： The primary topics in this part of the specialization are: data structures (heaps, balanced search trees, hash tables, bloom filters), graph primitives (applications of breadth-first and depth-first search, connectivity, shortest paths), and their applications (ranging from deduplication to social network analysis).
此课程适用人群： Learners with at least a little bit of programming experience who want to learn the essentials of algorithms. In a University computer science curriculum, this course is typically taken in the third year.

Amazing course! Tim Roughgarden is an exceptional teacher! I'm really enjoying reviewing this algorithms and data structures topics
I think this was the best course of the specialization. Stacks, queues, heaps, search trees, hash tables etc. are data structures everyone should know; when to use and their raison d'etre as he says.. and to that end this course is very effective. This course also has a very nice flow. And of course, Prof. Tim Roughgarden is simply awesome. I wish I got a chance to be in his offline classroom.
Good course, but instructor does start to move fast and a few walk-throughs in certain spots would be beneficial . However the lack of it makes you do your own research, which is also beneficial.
This course is very good! The professor explain the algorithms in detail , and the programming assignment is challenging！Highly recommend!
