WebSince G is a directed graph, d is not symmetric, and d(i,j) corresponds to the distance between nodes i and j.The Inf values in d correspond to nodes that are unreachable. For example, since node 1 has no predecessors, it is not possible to reach node 1 from any other node in the graph. So the first column of d contains many Inf values to reflect that … WebDiameter.java.
