Questions and Answers

What is the complexity of finding weakly connected components in a digraph?

  • Θ(n^2)
  • Θ(n)
  • Θ(e)
  • Θ(n + e) (correct)
  • How can a strongly connected component in a digraph be found?

  • By computing the connected components of the undirected version of the digraph
  • By ignoring the direction of edges in the digraph
  • By finding the largest subgraph of mutually reachable nodes
  • By repeatedly traversing the original graph and its reverse (correct)
  • What is the purpose of computing the reverse graph of a digraph?

  • To represent the inverse relation of the original graph (correct)
  • To ignore the direction of edges
  • To find weakly connected components
  • To increase the size of the graph
  • How is a connected component defined in an undirected graph?
