Question: Suppose that we are given a directed acyclic graph G = (V, E) with real-valued edge weights and two distinguished vertices s and t. Describe

Suppose that we are given a directed acyclic graph G = (V, E) with real-valued edge weights and two distinguished vertices s and t. Describe a dynamic-programming approach for finding a longest weighted simple path from s to t. What does the subproblem graph look like? What is the efficiency of your algorithm?
