Evangileon/NumberShortestPath

umber of simple shorest paths from a source node s to each node. The input is a directed graph G=(V,E) as input, with edge weights W:E-->Z (negative weights are possible). The output is the number of shortest paths (not necessarily disjoint) from s to each vertex u in the graph. If the graph has a negative or zero cycle, reachable from s, then print a message "Non-positive cycle in graph. DAC is not applicable".
