WebSay, the node is u, now traverse each node in the adjacency list of u. Say, the node is v (i.e. u -> v) . In the transpose graph, add u to adjacency list of v (there exists and edge from v to u i.e. v -> u). Repeat this process for all the nodes (& their respective adjacency lists) in the graph until the transposed graph has been obtained.

WebIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph.The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.. In the special case of a finite simple graph, the adjacency … WebAn adjacency matrix is a way of representing the relationships of these vertices in a 2D array. For unweighted graphs, if there is a connection between vertex i and j, then the value of the cell [i,j] will equal 1, if there is not a connection, it will equal 0. When graphs become weighted, the value of 1 is replaced with the "cost" of the edge ...
