Hi everyone!

I would like to invite you to participate in February Clash at HackerEarth. The contest is scheduled to start at February 11, 1200 hrs IST. The contest will last for 24 hours so everyone should be able to find some time to comfortably participate.

There will be six tasks in the problemset. Five of them are standard algorithmic problems with partial solutions allowed — you get points for every test that your solution passed. And the last task is an approximate problem — your score for this task depends on how good your solution is compared to the current best solution.

flatline, pkacprzak, Sokolov, r3gz3n and Abhinav Gupta are the authors of this problemset. All the testing was done by me, akulsareen

I hope that everyone from beginners to experienced contestants will be able to find some problem that challenges and interests them. In case you find all problems too easy there is always the approximate challenge to tackle.

As always, belowthebelt was a great help, and I would like to thank him for taking care of all the technical aspects of contest preparation.

While problem solving is rewarding enough on its own, there will be some added incentive for you to do well.

Top5 of leaderboard will receive some nice prizes:

1. $100 Amazon gift card + HackerEarth T-shirt

2. $75 Amazon gift card + HackerEarth T-shirt

3. $50 Amazon gift card + HackerEarth T-shirt

4. HackerEarth T-shirt

5. HackerEarth T-shirt

Good luck to everyone — hope to see you at the top of the leaderboard.

UPD: Contest is now over.
