Questions and Answers

What does a topological sort help to determine?

  • The longest path in a graph
  • The shortest path in a graph
  • The parallel edges in a graph
  • The order of precedence in a graph (correct)
  • In which type of graph is topological sort commonly used?

  • Connected graph
  • Undirected graph
  • Directed acyclic graph (DAG) (correct)
  • Complete graph
  • Why can't we sort the vertices of a cyclic graph using topological sort?

  • Because cyclic graphs do not have vertices
  • Because topological sort works only on complete graphs
  • Because cyclic graphs have parallel edges
  • Because topological sort cannot handle cyclic dependencies (correct)
  • What is a characteristic of the vertices in a graph that allows topological sorting to be possible?

    If a graph has parallel (multiple) edges between vertices, can we perform a topological sort on that graph?
