Concept explainers

Minimum Spanning Tree

A spanning tree is a sub-graph of a connected, undirected graph. It has all the vertices of a graph with the minimum possible number of edges. If a vertex is skipped, then it will not be a spanning tree. The edges of a spanning tree may or may not have weights.

Question

You see an adjacency list representation of a graph in Figure 2. Which choices are true?
a. There is an edge between 2 and 4
b. This cannot be a directed graph.
c. To find a path between 1 and 3, we can run BFS algorithm
d. The degree of node 2 is 1
