From 0 to 1 Data Structures & Algorithms in Java - Graph Using An Adjacency List And Adjacency Set

The video tutorial covers three main graph representations: adjacency matrix, adjacency list, and adjacency set. It explains the structure and use cases of each representation, focusing on the adjacency list and its implementation in Java. The tutorial also discusses the differences between directed and undirected graphs, the limitations of adjacency lists, and the advantages of using adjacency sets. Java code examples are provided to illustrate the implementation of these graph representations.

In what scenarios might an adjacency matrix be preferred over an adjacency list?

What is the significance of the order of vertices in an adjacency list?

How can the adjacency list representation lead to multiple valid representations of the same graph?

What is the role of the 'head' in a linked list representation of a node in an adjacency list?
