I have a hunch that you do not want to write the program, nor do you
want to see exactly how a programmer would write it?

The question is more like asking a heart surgeon how she performs
heart surgery:  you don't plan to do it yourself, but you want a
general idea of how it is done?  How do you keep the patient from
bleeding to death?  Does the heart stop while performing the surgery,
and if yes, how does the patient stay alive?
