AD INFINITUM - MATH PROGRAMMING CONTEST

Post by shanecruise »

Hello

I am a great fan of Project Euler since last many years. And I always felt the need for a programming based Math contest.
We at https://www.hackerrank.com have started a 4 Day long monthly Programming Contest based purely on Mathematical Concepts. Participants will be required to submit their code which will be evaluated against the test cases.

After the contest is over we will post detailed solutions, and other participants code will be public. So it's a great opportunity to learn.

Please note I have personally contributed problems and made sure the problem solving will be a good experience :)

Contest starts on March 28 to April 1 (Over the weekend). Open the link to know the local timings.
Register yourself at -> https://www.hackerrank.com/infinitum-mar14

You can code in any of the languages as mentioned here https://www.hackerrank.com/environment
The statements will be available in English, Russian, Mandarin, and possibly Japanese too

Looking forward to your participation.
For more details write to me at shashank@hackerrank.com

As this is a monthly contest I would also like to invite contribution from Project Euler community in terms of programming problems. So that the initiative can sustain in a collaborative way.
Problem setters/testers/translators will be paid by HackerRank. And their names will be displayed on main contest page.

Looking forward to your participation and contribution
Thanks a Lot

Just a little question shanecruise.
It seems that hackerrank wants to make the participants' code public.
How come you never contributed your solutions to PE's problems fora and doing so withheld from PE's members your valuable insights?
I'm sure that would have meant a great learning experience for us all.
I'm a little bit afraid you're not entirely honest regarding Project Euler and its participants.

Hi hk

You are absolutely right and I accept that I have been on the selfish side that I learnt a hell lot from PE but never contributed back.
All i can say is I blame it on my hesitations that my solution would be a brute or someone already has a better solution.

Going forward I promise my engagement with PE would be more engaged.

Thank you hk for pointing that out to me.

Last month Infinitum was a great success :)

Register for Infinitum April'14
https://www.hackerrank.com/infinitum-apr14

You can view the last month's challenges here: https://www.hackerrank.com/infinitum-mar14/challenges This month, the problems are much more interesting, have more variety and are a little more difficult.

I'm very thankful to kevinsogo for testing problems.

Looking forward to your participation. If you have queries, feel free to ask here.


Thanks

In the problem "A Chocolate Fiesta", there is a major mistake. In the note section, the set A has two elements, not three. In the structure called set, it doesn't matter, how many times an element is listed. So {2,2,3}={2,3}. That means its power set has 4 elements, not 8.

You are right, the word set is not used as mathematical set. And we noticed it after the contest began hence we made note on to how to interpret the statement here.
Also the sample was added so there is no confusion.

Still I feel that the contest is over the statement can be fixed now.

Thanks

From the example it was clear what you meant, I just wanted to correct it. As mathematicans and programmers, we all should try to do our best to make precise statements.
