Hello everyone!

I would like to invite you to participate in Hackerearth May Circuits 2017. It's a long contest that will start on May 19, 2017, 09:00 PM IST (check your timezone). Contest will run for 9 days.

The problemset consists of 7 traditional algorithmic tasks of various difficulties 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 — thanks to architrai, Arterm, harshil and imamit for preparing these tasks. editorials will be provided to you by saatwik27

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

• $100 Amazon gift card + HE t-shirt.
• $75 Amazon gift card + HE t-shirt.
• $50 Amazon gift card + HE t-shirt.
• HE t-shirt.

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