Revision en24, by alooochaat1998, 2018-03-19 15:28:54

Hello, Codeforces!

I would like to invite you all to Alkhwarizm 2018, the flagship coding event of Aparoksha — The Annual tech fest of IIIT-Allahabad.

It will contain 10 tasks of varying difficulty and you will get 5 hours of time to fight this fierce battle of Codditch(another version of Quidditch).

The contest will be an External rated contest. We are happy to announce that Alkhwarizm 2017 was the first External rated contest in the history of Codechef and this year Alkhwarizm 2018 is the first External rated contest for both Divisions after the New Rating Division system on Codechef.

The problem setters and testers are me(alooochaat1998), blake_786 and priyanshupkm. Buckle up for an adventure ride through the wizarding world of Harry Potter once again. Each problem you solve will score a goal. Score all goals in this fierce battle of Codditch and we'll make sure that you get the lion's share in Monex Melicis (the money potion, another version of Felix Felicis).

The contest starts at 9:00PM (IST) on 16th March,2018. Check your timezone here.


  • The best wizard/witch will get a lion's share of 10K INR.

  • The 2nd best wizard/witch will get a panther's share of 6K INR.

  • The 3rd best wizard/witch will get a wolf's share of 4K INR.

  • Top 5 global winners and top 5 Indian winners will get 300 laddus each straight from the kitchen of Honeydukes.
