Hello Community,

It gives me immense pleasure to invite you all to yet another coding contest by HackerEarth called Data Structures and Algorithms (DSA). This is a 1.5 hour contest with 3 questions to solve.

The problems of April 2020 edition are classic and educational as against being creative and challenging. So, if you're learning new things, don't miss the DSA contests.

Problem setting panel includes Sparsh Sanchorawala spar5h, Robin Singh _fUncTiOn and Rishabh Kejariwal RishabhKejariwal.

Tester for the Contest is AmirReza PoorAkhavan Arpa.

The contest would go live on April 11th 4:00AM UTC

Link to the contest!!!

Good Luck & High Ratings!!!

PS:

This is a rated contest.

There are no prizes for this contest.

Hi everyone,

I would like to invite you to participate in HackerEarth's October Easy'19. The contest will start at 04:00 UTC, October 05, 2019

The problems are prepared by me, slappy , TheOneYouWant , Vivek1998299 and vamaddur 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!
