Total Neighbors
The algorithm counts the total number of neighbors, or vertices connected by one hop, of two vertices.

Example
Suppose we have the following graph.
Dan and Jenny together have 6 neighbors in total.
Dan’s neighbors are:

Nancy

Kevin

Tom

Jenny
and Jenny’s neighbors are:

Dan

Tom

Amily
Running the algorithm with input vertices of Dan
and Jenny
would give us a result of 6
because the connection Dan  Jenny and Jenny  Dan is not doublecounted.
