Give an example of a weighted directed graph G = (V, E) with weight function w : E R and source vertex s such that G satisfies the following property: For every edge (u, v) E, there is a shortest-paths tree rooted at s that contains (u, v) and another shortest-paths tree rooted at s that does not contain (u, v).
