8. (15 pts) Two special vertices s and t in the undirected graph G=(V,E) have the fol- lowing property: any path from s to t has at least 1 + |V |/2 edges. Show that all paths from s to t must have a common vertex v (not equal to either s or t) and give an algorithm with running time O(V+E) to find such a node v.
