Hello Codeforces Community!

I invite you all to take part in HackerEarth's December Easy, scheduled on the 1st of December at 22:00 IST.

Problems have been set by me(paradox1) and tested by satyaki3794. We are grateful to HackerEarth admin r3gz3n for his help.

You will be given 5 algorithmic problems to solve in 3 hours. Partial scoring will be used (you get points for passing each test case). Although the contest is targeted towards beginners, we hope even experienced problem-solvers find one or two problems to be interesting. The contest is rated and prizes will be awarded to the top 3 beginners(i.e. Programmers with a rating of 1600 or less before the challenge starts).

I hope you have fun solving the problems. You can discuss problems on this thread after the contest.

Good luck and have fun.

Hello Codeforces Community!

I would like to invite you to take part in Ittiam "Think" Challenge, scheduled to start on the 13th of August at 12:00 PM IST.

You will be treated with some interesting set of problems which are set by MazzForces, AlexandruValeanu, saatwik27 and send_nodes. It was real challenge to solve and test them for me(paradox1).

So get your weekend booked to solve some intriguing problems. The contest will be slightly on the harder side, few challenging problems for high experts and div1 contestants, but others too will find them interesting. So buckle up for maximum participation, as there are great prizes to be won.

I hope you will enjoy solving the problems. You can discuss and provide feedback about them in comment section below after the contest.

UPD : Note that prizes will only be for Indians. In addition, keeping up with previous issues with challenges with prizes, this is an open challenge running for 7 hours, without any slots, with a better problemset, to ensure the prizes to go the people who deserve them.

UPD2 : The Contest has ended, Congrats to the winners.
