Hello everyone!

I would like to invite you to participate in Hackerearth April Circuits 2017. It's a long contest that will start on April 21, 21:00 IST (check your timezone). Contest will run for 8 days.

The problemset consists of 7 traditional algorithmic tasks and 1 approximate problem. For traditional algorithmic tasks, you will receive points for every test case your solution passes — so you can get some points with partial solutions as well. For the approximation task, your score depends on the best solution in the contest so far. Check contest page for more details about in-contest schedule and rules.

I'm the tester of the problemset you'll have to work on — thanks to jtnydv25, saatwik27, pkacprzak, r3gz3n, trytolearn for preparing these tasks.

As usual, there will be some nice prizes for the top five competitors:

1. $100 Amazon gift card + HE t-shirt.
2. $75 Amazon gift card + HE t-shirt.
3. $50 Amazon gift card + HE t-shirt.
4. HE t-shirt.
5. HE t-shirt.

Good luck to everyone, and I hope to see you at the contest :)
