On a Functional-Difference Equation of Runyon, Morrison,
Carlitz, and Riordan
A certain functional-difference equation
that Runyon encountered when analyzing a queuing system
was solved in a combined effort of Morrison, Carlitz,
We simplify that analysis by exclusively
using generating functions, in particular
the kernel method, and the Lagrange inversion
