What is an adjacency matrix - Javatpoint

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 ...
