WebNote: Whenever you are trying to implement any graph related problems, I would strongly suggest you to not make use of adjacency matrix. Rather make use of adjacency list to represent your graph. Because, adjacency matrix takes O (V^2) space where V is the number of vertices in the graph. WebSo far, we have discussed the use of adjacency matrices in the representation of graphs, an alternative method would be the implementation of an adjacency list. An adjacency list is similar to an adjacency matrix in the fact that it is a way of representing a graph, however it uses linked lists to store the connections between nodes. WebAn adjacency matrix is initially developed to represent only unweighted graphs, but in the most effective way possible - using only one array.
