degreeOut -- returns the "out-degree" of a vertex in a digraph

Synopsis

Usage:

x = degreeIn (D, v)
Inputs:
- D, an instance of the type Digraph,
- v, a thing, a vertex of D
Outputs:
- x, an integer,

Description

In a directed graph, we define the degree out of a vertex or the "out-degree" of a vertex to be the number of children of that vertex. Intuitively, this give the number of edges pointing out of a vertex to another vertex.

i1 : D = digraph({1,2,3,4},{{1,2},{2,3},{3,4},{4,2}});

i2 : degreeOut(D, 2)

o2 = 1
