Shortest ancestral path. Given a DAG and two vertices v and w, find the shortest ancestral path between v and w. An ancestral path between v and w is a common ancestor x along with a shortest path from v to x and a shortest path from w to x. The shortest ancestral path is the ancestral path whose total length is minimized. Warmup: Find a DAG where the shortest ancestral path goes to a common ancestor x that is not an LCA. Hint: Run BFS twice, once from v and once from w
