In a graph, a path is a sequence of vertices such that each vertex is connected to the next by an edge. If the last vertex is connected to the first vertex, then the path is called a circuit.
Which of the following is a path in the graph below?
A -- B -- C -- D -- E
Which of the following is a circuit in the graph below?
A -- B -- C -- D -- E F -- G -- H
In a graph with $n$ vertices and $m$ edges, the maximum number of paths between two vertices is:
In a graph with $n$ vertices and $m$ edges, the maximum number of circuits is:
A graph is called a connected graph if there is a path between every pair of vertices. Which of the following graphs is connected?
A -- B -- C D -- E -- F
A graph is called a tree if it is connected and has no cycles. Which of the following graphs is a tree?
A -- B -- C D -- E -- F
In a graph, a spanning tree is a tree that includes all the vertices of the graph. Which of the following graphs is a spanning tree of the graph below?
A -- B -- C D -- E -- F
In a graph, a Hamiltonian path is a path that visits every vertex exactly once. Which of the following graphs has a Hamiltonian path?
A -- B -- C D -- E -- F
In a graph, a Eulerian circuit is a circuit that visits every edge exactly once. Which of the following graphs has an Eulerian circuit?
