Write a DFS algorithm to find the bridges and cut vertices of a connected, undirected graph in linear time (Problem 22-2, parts d, f). Articulation points, bridges, and biconnected components Let G = (V, E) be a connected, undirected graph. An articulation point of G is a vertex whose removal disconnects G. A bridge of G is an edge whose removal disconnects G. A biconnected component of G is a maximal set of edges such that any two edges in the set lie on a common simple cycle. Figure 22.10 illustrates The articulation points, bridges, and biconnected components of a connected, undirected graph for use in Problem 22-2. The articulation points are the heavily shaded vertices, the bridges are the heavily shaded edges, and the biconnected components are the edges in the shaded regions, with a bcc numbering shown. d. Show how to compute all articulation points in O(E) time. f. Show how to compute all the bridges of G in O(E) time
