Assume a graph G is simple (ie. no self loop or parallel edges). Let v be any vertex in the graph. Let boolean[] marked be initalized to all false. Consider: boolean dfs(Graph G, int v) { } marked[v]= true; for (int w G.adj(v)) { if (w == u) continue; if (marked[w]) return true; if (dfs (G, v, w)) return true; } return false; If the call dfs(v) returns true, then: a. The graph has cycles b. The graph is bipartite c. The graph is connected Not enough information b a
