Question
Consider the following undirected graph:
A
/ \
E D
\ /
C
|
B
Which of the following is a valid adjacency list representation of the above graph?
Solution
An adjacency list representation of a graph is a way of representing the graph where each vertex has a list of vertices that it is connected to.
For the given graph, a valid adjacency list representation would be:
A: E, D B: C C: B, E, D D: A, C E: A, C
Explanation:
- Vertex A is connected to vertices E and D.
- Vertex B is connected to vertex C.
- Vertex C is connected to vertices B, E, and D.
- Vertex D is connected to vertices A and C.
- Vertex E is connected to vertices A and C.
