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 9 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.
