in an orderly manner. If the two points are connected by edges, the elements in the matrix are 1, and the opposite is 0. You can understand the instance ~ For an undirected graph, the sum of the lengths of all adjacent tables is 2 | E |. For a directed graph, | E | (each edge of an undirected graph is expressed twice) It has potential limitations. To determine whether an edge (u, v) exists, you can only search for v in the table Adj [u. If yes, yes,
