(SHOW ALL YOUR WORK, not just the answers) When you multiply: 21 x 68 you most likely do: 8x1 + 8x20 + 60x1 + 60x20 = 1, 428 So, there are 4 multiplications and then 3 additions. How long would it take a computer to do t ...

Q: Undirected vs. directed connectivity. (a) Prove that in any connected undirected graph G = (V, E) there is a vertex v ? V whose removal leaves G connected. (Hint: Consider the DFS search tree for G.) (b) Give an examp ...
