Question 6: (10 points) Consider a network G with a start node s and a destination node t. We want to find a path to minimize the total cost from node s to node t. We model this problem as a shortest path problem and plan to use Dijkstra algorithm to solve it. During solving, we just realize that the cost of one arc is negative. The cost of all other ares is nonnegative. (a) (5 points): Will Dijkstra algorithm be able to find the optimal solution? If yes, why? If no, why not
