Let G be a directed, acyclic graph with n vertices. Assume that the vertices are numbered 0 through n 1 such that all edges are of the form < i, j >. where i < j. Assume that the graph is available as a set of adjacency lists and that each edge has a length (which may be negative) associated with it. Write an algorithm to determine the length of the short- est paths from vertex 0 to the remaining vertices. The complexity of your algorithm should be O(n + e), where e is the number of edges in the graph.
