(25 Points) Give an example of a directed graph G = (V, E), a source vertex s e V, and a set of tree edges Em C E such that for each vertex v EV, the unique simple path in the graph (V, ER) from s to v is a shortest path in G, yet the set of edges Er cannot be produced by running BFS on G, no matter how the vertices are ordered in each adjacency list.
