- saagarjha 8y agoYup we tried that ;) Unfortunately, during the competition we were having some issues getting the Internet Archive to work–apparently there was some sort of bug when showing the list dates that the page had been cached, so the way to grab it was to guess a date and pick a day from there (which has since been fixed). Of course, we found this out a couple of days after getting the solution with a combination of brute force and the application of clever constraints.
