Data Structures and Algorithms The Complete Masterclass - Graphs

The video tutorial explores graphs as a crucial data structure, highlighting their importance in coding interviews, implementation, and real-life applications. It explains the basics of graphs, including nodes, edges, and vertices, and contrasts them with trees. The tutorial covers different types of graphs, such as directed, undirected, weighted, and unweighted, and discusses their use cases in social media, ecommerce, and algorithms. It also explains methods for storing and implementing graphs, including adjacency matrices, lists, and edge lists.
