Give a linear-time algorithm that takes as input a directed acyclic graph G = (V, E) and two vertices s and t, and returns the number of simple paths from s to t in G. For example, the directed acyclic graph as given in Q8 contains exactly four simple paths from vertex p to vertex v, pov, poryv, posryv, and psryv. (Your algorithm needs only to count the simple paths, not list them.)
