Depth first search discovery finishing time
WebDFS returns, every vertex u has been assigned a discovery time d[u] and a finishing time f[u]. In each DFS-visit(u) call, vertex u is initially white. Line 1 paints u gray, and line 2 records the discovery time d[u] by incrementing and saving the global variable time. Lines 3-6 examine each vertex v adjacent to u and recursively visit v if it ... WebIn the following graph, discovery time stamps and finishing time stamps of Depth First Search (DFS) are shown as x/y, where x is discovery time stamp and y is finishing time stamp. It shows which of the following depth first forest? {a, b, e} {c, d, f, g, h} {a, b, e} {c, d, h} {f, g} {a, b, e} {f, g} {c, d} {h} {a, b, c, d} {e, f, g} {h}
