'Algorithm to determine whether all points are not Source points by attaching a direction to each edge
Given an undirected graph G(V,E), design an algorithm to determine whether all points are not Source points by attaching a direction to each edge (Note that the Source point means the point does not have any incoming edges) eg.enter image description here
