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.

TOP REVIEWS FROM UNORDERED DATA STRUCTURES
A lot of new concepts learned. However I would have like to do more programming, exploring more features of C++. Changing only one or two lines of an existing code does not help much in our learning.
Great course! Very interesting lecture material / content. I can't give this course a five however, as the assignments seem unnecessarily convoluted, and abstracted to demonstrate the material.
Overall, great course. Slightly obscure challenges sometimes, but homeworks were awesome because of how well commented all the provided code was. Instructor and videos were also amazing!
Could have been a bit more explanatory for people not from CS background. Typos and mistakes should have been eliminated to the largest possible extent. Leaving these aside, nice course.
