WebDec 31, 2024 · Suppose we run the Floyd-Warshall algorithm on a directed graph G = (V,E) in which every edge's length is either -1, 0, or 1. Suppose further that G is strongly connected, with at least one u-v path for every pair u,v of vertices. The graph G may or may not have a negative-cost cycle. WebDec 2, 2024 · Given a directed graph, find out if a vertex j is reachable from another vertex i for all vertex pairs (i, j) in the given graph. Here reachable mean that there is a path from vertex i to j. The reach-ability matrix is …
