WebCreating an adjacency list representation of a directed graph In an adjacency list representation, linked lists are used to represent the adjacent vertices of a vertex. That is, a separate linked list is made for the adjacent vertices of each vertex, and, in the end, all the vertices of the graph are connected. WebEdge List Representation. An edge-list representation of a graph is simply a sequence of edges, where each edge is represented as a pair of vertex ID's. The memory required is only O(E). Edge insertion is typically O(1), though accessing a particular edge is O(E) (not efficient). Figure 5 shows an edge-list representation of the graph in Figure 1. canadian flag cell phone case
