In a digraph, the sum of the in-degrees is equal to:A. The number of verticesB. The number of edgesC. Twice the number of verticesD. Twice the number of edges
Question
Solution 1
The correct answer is B. The number of edges.
Here's why:
In a directed graph (or digraph), each edge has an initial vertex and a terminal vertex. The in-degree of a vertex is the number of edges for which that vertex is the terminal vertex.
