A directed grаph G is shоwn belоw. Assume we аre using аdjacency lists as the graph representatiоn. We further assume that the vertices on the adjacency lists are listed alphabetically. Apply depth-first search (DFS) on the graph. In the main-loop of DFS, check the vertices in alphabetical order. During the computation, the algorithm computes values v.d, v.f, and v.
