The 2016 ACM-ICPC North America Qualification Contest will be held tomorrow, Saturday, at 16:00 UTC. The duration is 5 hours.
There will be a simultaneous open contest, held on Kattis.
For approximate difficulty, you can find the 2015 problem set here.
Contest is over. Test data and solution explanations posted here.
Are model solutions (codes) available? And problemset as PDF?
You can find the problem set PDF here, but I don't think model solutions will be posted. We do, however, have solution slides (found on the webpage linked above), which is a first for NAQ. One step at a time. :)
