New Programming problems. 1. The warshall algorithm computes the all-pairs shortest paths of a directed graph. It also gives us the "next-hop" matrix. For this matrix (N), if N[i][j]=k then vertex k is the next vertex along the shortest path from i to j. If no path exists, then N[i][j]==i. You are to write a function void printpath(int ** N, int n, int i, int j) which, given the final next-hop matrix, it's size (nXn) and start and destination vertices (i and j), should print the nodes that should be visited on the shortest path from i to j, or "no path" if none exists. I will add more problems to this set later.
