What's so useful about that?
- hammock 2y agoSlows you down if I had to guess
- mbreese 2y agoIf your copies come out of the machine right-side up and they get stacked on top of each other, then you can just take the finished stack from the machine when finished. Otherwise, you’d have to reverse the stack, which in real life or in a computer is an expensive operation.
- albert_e 2y agoThe photocopies come out stacked in the right order maybe?
- bee_rider 2y agoThis would be a kind of interesting data structure. A stack, FILO, but you can flip it for reading (maybe flip is an expensive operation).
- byteknight 2y agoGrass is good.
- Propelloni 2y agoOthers already said it, but yeah, the copies came out ready-to-read. The university had, IIRC, Sharp copiers which put out the copy right-side up.
