2. Suppose that we are given a weighted, directed graph G=(V, E) in which edges that leave the source vertex s may have negative weights, all other edge weights are nonnegative, and there are no negative-weight cycles. Is Dijkstra's algorithm still correct in finding shortest paths from s in this graph? Explain.
