Each vertex has an indegree and an outdegree

For a vertex, the number of head ends adjacent to a vertex is called the indegree of the vertex and the number of tail ends adjacent to a vertex is its outdegree (called branching factor in trees). Let G = (V, A) and v ∈ V. The indegree of v is denoted deg (v) and its outdegree is denoted deg (v).
