I am the author of problems and editorials, while Errichto is the tester. There are also some other people who helped with translations and miscellaneous issues who I will fill in later.
There is no registration required, anybody with a CodeChef handle can participate. Top participants can win CodeChef laddus (details on the contest page).
You will be provided 5 problems. There's one problem that shows a style of problems I would like to see more in competitions. Let me know what your thoughts are after the contest.
Hope to see you all on the leaderboard!
