Chapter: 29 / Q: 19
(Find u with smallest cost[u] efficiently) The getShortestPath method finds a u with the smallest cost[u] using a linear search, which takes O(V)
Chapter: 29 / Q: 20
(Test if a vertex u is in T efficiently) Since T is implemented using a list in the getMinimumSpanningTree and getShortestPath methods in Listing 29.2 WeightedGraph.java, testing whether a vertex u is in T by invoking T.contains(u) takes O(n) time
