7. Most valuable node. You are given a directed graph G

7. Most valuable node. You are given a directed graph G = (V, E) in which each node v E V has an associated value clv, which is a positive number. You are also given a node s V Your goal is to find the most valuable node v that is reachable from s. That is, among all nodes v reachable from s, find one for which c[v] is largest. Your algorithm should run in linear time. Hint: solve the problem first assuming the graph is acyclic; use standard algorithms as subroutines
