Graph Representation: Adjacency List and Matrix

WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time. WebAn adjacency matrix is a V × V array. It is obvious that it requires O ( V 2) space regardless of a number of edges. The entry in the matrix will be either 0 or 1.
