abstract:A sorting network is an abstract mathematical model of a network of wires and comparator modules that is used to sort a sequence of numbers. Each comparator connects two wires and sorts the values by outputting the smaller value to one wire, and the larger to the other.
It already has a far-flung network of sorting centers and letter carriers that allows it to deliver physical documents to every U.S. address six days every week.
Not to mention, they have to spend a lot of time sorting out family issues arising from home network failure, plus shouldering all the grief from relatives and friends.
