By belowthebelt, history, 9 years ago, In English

Hello everyone,

I want to invite you to participate in HackerEarth July Easy Contest '15. It is 3 hour long contest scheduled on July 1. Check your timezone: http://hck.re/iZy4VB

The link to the contest: https://www.hackerearth.com/july-easy-15/

The problem set consists of 6 algorithmic tasks with partial solutions allowed — you get points for every test that your solution passes. The problem set was prepared by me, tested by FatalEagle and the editorials are presented by pkacprzak.

Top 5 beginners of the leaderboard will also get a HackerEarth T-shirt!

Good luck, everyone!

Update1: The contest has been on for 30 minutes now, guys! I hope everyone enjoys the storyline of the problemset, too. :)

    It's an easy challenge, Yunus. But, we've tried our best to make it interesting for everyone. The advanced users can try solving all the problems as quickly as possible to challenge themselves! :)

What is the eligibility criteria for winning the T shirt ?
How do you identify "beginners"?
Will I fall in that category? (I think I do) :P
P.S — I have completed my first year

The Falling Eagle problem from this round was almost the same with Xsquare and Array Operations from Awesome April. I want to think the situation as two people creating the same problem independently, otherwise this is just unacceptable. For a problem to be easy, it doesn't need to be copied from somewhere else. Easy problems should also be unique. (Please inform me if I'm mistaken here.)

    Yes, you're right determinism, this is not acceptable — at all. And I want to assure you that this was NOT on purpose. This is just a co-incidence. (Terrible one, though!)

    I just saw both the problems now, and yes, they're creepily, extremely similar. I'm so, sorry for this to happen. I apologize from my end that I let this happen. I had created this problem way back in 2014. And it was not used still. Though, the author/tester team for both the problems had extremely different ideas and reasoning behind the same problem. But that's no reason for this to happen: I've no excuses, this was my fault: I'm sorry!

    I'll be more careful from now on regarding this!

    Moreover, dont you think that [6th] problem was very straight forward? It was simple catalan numbers which is also mentioned in the wikipedia article. [Dyck's problem] I dont remember but I also saw same problems while practicing on different OJs. So, Determinism is right regarding the easy problems which should be unique.
