Hello everyone!↵
↵
I would like to invite you to participate in HackerEarth [January Circuits](https://www.hackerearth.com/january-circuits-17/). It's a long contest that will start on January, 20, 21:00 IST ([check your timezone](https://www.timeanddate.com/worldclock/fixedtime.html?msg=HackerEarth+January+Circuits+-+17&iso=20170120T21&p1=438)). Contest will run for 8 days.↵

The participants will be challenged by multiple Problem Setters with 7 traditional algorithmic tasks and 1 approximate problem of varying difficulty levels in a duration of 8 days. 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. Here is the detailed time line of the challenge,↵
↵
- **Day-0** : Problem-1 (Easy) , Problem-2 (Medium), Approximate↵
- **Day-2** : Problem-3 (Easy-Medium) , Problem-4 (Medium-Hard)↵
- **Day-4** : Problem-5 (Easy-Medium) , Problem-6 (Medium-Hard)↵
- **Day-6** : Problem-7 (Hard)↵
- **Day-7** : Challenge Ends↵

I am one of the Problem Setters. I'd like to thanks [user:prat33k,2017-01-19], [user:vaibhavjaimini,2017-01-19], [user:gamer12,2017-01-19] and [user:lewin,2017-01-19] for preparing the tasks, [user:fataleagle,2017-01-19] for testing them and [user:MikeMirzayanov,2017-01-19] for creating Polygon.↵

The contest will be **RATED**.↵
↵
Happy Coding :) ↵
↵
**UPD:** Problem-3 and Problem-7 will not have partial scoring.↵
↵
**UPD1:** Solutions of the Setter and Tester was wrong for Problem 7. This is a big mistake from our side. We are sorry for the inconvenience. Due to this, the January Circuits will be **UNRATED**. Regarding the prizes, we will distribute the prizes on the basis score of the other 7 problems.
