About this course: 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).
Who is this class for: 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.

Ratings and Reviews
This course is very good! The professor explain the algorithms in detail , and the programming assignment is challenging！Highly recommend!
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.
