Meta Hacker Cup Round 3

Good morning! Meta Hacker Cup Round 3 starts on Saturday, October 8th in under 48 hours! You're automatically registered for Round 3 if you placed in the top 500 of Round 2.

Important info:

You'll qualify for the Hacker Cup Finals if you place in the top 25 in this round.
If you place in the top 200 of this round, your Hacker Cup shirt will have a badge on the sleeve indicating you did so.
The round will be 3 hours long.

Though we attempt to sort the problems in ascending order of difficulty and assign point values appropriately, we particularly encourage reading all the problems in this round.

A separate post about t-shirt distribution will be coming in the next few days. Good luck, have fun, and we'll see you on the scoreboard!
