Hello Codeforces!

I would like to invite you to CodeCraft-18, which will take place on Saturday, 20th January, 9:05 PM IST. This is a combined Div. 1 + Div. 2 round and is rated for participants of both divisions.

CodeCraft-18 is part of Felicity, IIIT Hyderabad's most awaited set of events, Threads. With a plethora of intellectually engaging online contests in various fields of programming, mathematics and general knowledge, Threads is a celebration of the spirit of computing and engineering. Other than CodeCraft, we have the Project Euler-style contest Gordian Knot and a jeopardy-style CTF event called Break In, amongst other events.

I would like to thank the CodeCraft team -- FundamentalEq, RohanRTiwari, additya1998, aman_shahi2, born2rule, codelegend, crvineeth97, deepanshugarg, devanshg27, mprocks, nir123 and virus_1010 -- for their amazing work in problemsetting. I would also like to thank gritukan for helping us prepare the problems, and MikeMirzayanov for the great Codeforces and Polygon platforms.

Prizes

  • Top 20 participants win Codeforces T-shirts
  • Top 5 participants from India win Codeforces T-shirts

You will be given 8 problems and 3 hours to solve them. The scoring distribution will be announced later. Good luck!
