What are different methods of implementing graph?
As we have discussed, the two most common ways of implementing graphs are using adjacency matrices and using adjacency lists. We tend to prefer adjacency matrices when the graphs are dense, that is, when the number of edges is near the maximum possible number, which is n 2 n^2 n2 for a graph of n n n nodes.
