Hello everyone!

I would like to invite you to participate in January Circuits '18. It's a long contest that will start on Jan 20, 9:00 PM IST (check you 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 setter of the problemset and Kmcode is the tester. I would like to thanks HackerEarth admin dextrous for his help.

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 :)
