Problem 2: As we discussed in class, one can use an algorithm for computing all-pairs shortest paths to also compute the transitive closure of a graph. If using Floyd-Warshall for example, it is possible to do this in On") time (where as usual n is the number of nodes and m is the number of edges). Show how to compute the transitive closure of a directed graph in O(nm) time. For which type of graphs is this better than using...
