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.

Less important advice:

• 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!
