Intcode is a simple virtual machine language devised for the advent of code programming challenge. It is comprised of a sequence of integer values, separated by commas.
A quine is a program which outputs its own source code.
A Ruby VM implementation to run Intcode is available here: https://github.com/seanhandley/adventofcode2019/tree/master/ruby/vm
