Stаndаrd disclаimer: yоur sоlutiоn should use the algorithms from class (DFS, Explore, BFS, Dijkstra’s, Bellman-Ford, Floyd-Warshall, SCC, Kruskal's, Prim's, Ford-Fulkerson, Edmonds-Karp, and 2-SAT) as a black box subroutine for your algorithm. If you attempt to modify one of these algorithms you will not receive full credit, even if it is correct. Make sure to explain your algorithm in words (no pseudocode!), explain the correctness of your design, and state and analyze its running time. Faster—and correct—solutions are worth more credit. Computopia has n cities and m highways. Each highway connects two cities A and B. The highways were designed in a way such that it is possible to travel between any pair of cities (though you may need to pass through other cities along the way). To travel along highway h, you need to pay a toll price c(h)>0. The Central Highways are a subset of the highways such that: It is possible to travel between any two cities using only highways in The Central Highways. The sum of all the tolls c(h) of The Central Highways is the minimum possible. Britus, democratically elected president of Computopia, wants to update a part of The Central Highways. She changes the toll price of exactly one highway in The Central Highways, and asks her team to update The Central Highways to satisfy conditions (1) and (2) above. Given the original set of Central Highways, the one highway which is to be modified and its updated toll price, design an algorithm to find the updated Central Highways. You may assume the map data is already available as a graph in adjacency list format and that the toll price of any particular highway can be accessed in constant time. (Hint: there are two cases to consider, depending of the new toll price value.)
