Hi everyone,

I would like to invite you to participate in HackerEarth's July Easy'19. The contest will start at 04:00 UTC, July 07, 2019

The problems are prepared by me, FarFromRed, Danylo99 and AJ_Coder and tested by Arpa. I hope you'll find the problemset to be interesting.

You will be given 6 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) — $75, $50 and $25 Amazon gift cards respectively. In addition, there are T-shirts for the top 10.

Good luck & high ratings!

Upd: Contest starts in 30 minutes!

Upd2: Contest has ended.

Winners:

  1. Deemo

  2. neal

  3. chemthan

Congratulations to winners.
