Hello everyone

I would like to invite you all to the March HackerEarth Clash starting in around 28 hours (link to register here, check your time zone here). The contest will last 24 hours.

There will be five algorithmic problems and one approximation (optimization) problem. Read the problems for details on partial scoring for easier subtasks. I tried to make this clash interesting and challenging for everyone. That's my first clash, so I hope I've chosen difficulty right =)

I would like to thank Lewin for all his help in testing, editing statements, and writing editorials, and belowthebelt for all his help with the round.

There will be prizes — t-shirts and Amazon gift cards.

Hope to see you all at the contest!

UPD: contest stars in 15 minutes!
