WebBut, for a graph like 0->2->3->1. It wouldn't be able to compute the shortest between 0 and 1 because in starting it doesn't know the shortest distances from 0 to 3 or 2 to 1 in the distance matrix. In dynamic algorithms, we start from shorter problems and then use them to compute solution to larger problems. Web(a) Gets the name of a highway graph file from the command line. arguments.
