課程概述

The Unordered Data Structures course covers the data structures and algorithms needed to implement hash tables, disjoint sets and graphs. These fundamental data structures are useful for unordered data. For example, a hash table provides immediate access to data indexed by an arbitrary key value, that could be a number (such as a memory address for cached memory), a URL (such as for a web cache) or a dictionary. Graphs are used to represent relationships between items, and this course covers several different data structures for representing graphs and several different algorithms for traversing graphs, including finding the shortest route from one node to another node. These graph algorithms will also depend on another concept called disjoint sets, so this course will also cover its data structure and associated algorithms....

This course had good coverage on hashing, disjoint sets, graphs. This course will improve coding skills.\n\nI'm happy with material, coding practices, quiz and projects.

An insanely good course in which the instructors and professors put in the maximum possible amount of work for the student's benefit and clarity. Learnt a ton!

I've finished all three courses in this specialization. They are all great overall. However while studying the third course I feel like it's not well organized as the first two courses. There are some errors in the video that are not corrected yet, with only a few pages of note inserted into the video. And I think the most important part in this course is the run time analysis. But somehow the professor just went through them very quick with only a few words of explanations. I have to check back the old slides and the forums to read the explanations provided by the assistants. It gave me an impression that the professor just want to finish each topic as fast as he can.

So many errors in the video which distract students from learning the material. Makes me wonder about the quality of the online MS program by UIUC

The concept of the mentioned data structures are clearly delivered. But there is a gap between concepts and implement of C++ codes.

More theory discussed along the course but there are not many examples and the difficulty increases a lot.

Exceptional course! Lots of theory involved!.

Week 4 challenge seems to have been designed in a rush

The lectures were only mildly informative and the assignments give too much hand holding to even be considered a challenge at all

I feel the course has failed to effectively provide the students the rigor required to fully utilize and understand the power of data structures. Also, some real world examples on applications of data structures would go a longer way than simply academic ones
