Due to the availability of Simple equation problem on another platform, we have removed it from October Circuits '18. We are sorry for the inconvenience caused


Circuits is a coding marathon to challenge developers with several programming questions of varying difficulty level over 9 days. The questions are created by multiple problem setters from our developer community. Bring to light your logical minds by solving algorithmic programming problems.

Circuits take place during the third and fourth week of every month.

October Circuits’18 challenges you with 8 problems and the timeline is as follows:

Day - 0 Problem 1 (Very easy), Problem 2 (Easy-medium), Problem 3 (Approximate)
Day - 1 Problem 4 (Medium), Problem 5 (Medium-hard)
Day - 4 Problem 6 (Medium-hard) Problem 7 (Medium)
Day - 6 Problem 8 (Hard)
Day - 9 Challenge ends

New problem statements will be published every 48 hours, and yes, ace coders will win amazing vouchers.

This is a rated contest with prizes for the top three coders.

The top 5 candidates (with ratings less than 1600 before the challenge begins) will be given amazing HackerEarth t-shirts. :)
