Partial Question 8 5 / 10 pts Check all that apply. DFS(G) 1 for each vertex u E G.V 2 u.color = WHITE 3 u. = NIL 4 time = 0 5 for each vertex u E G.V 6 if u.color == WHITE 7 DFS-VISIT(G,u) DFS-VISIT(G,u) 1 time = time + 1 2 u.d = time 3 u.color = GRAY 4 for each v G. Adj[u] 5 if v.color == WHITE 6 V. = u 7 DFS-VISIT(G,V) 8 u.color = BLACK 9 time = time +1 10 u.f = time These operations take O(1El) time during the execution of DFS. for loop in Lines 4-7 in DFS-VISIT(G,u) set a vertex white set a vertex black checking if v.color == white (Line 5 in DFS-VISIT(G,u)) None of these answers
