Hello Codeforces! I am glad to present to you a new mashup composed of problems from various April Fools Day contests!I have selected what I consider to be the best and most solvable problems and gathered them into a single contest. I did my best to pick tasks that can either be solved straight away or require just a little bit of brute force — you won't see problems like this one which require massive brute force. Please do not look up or steal solutions from others, solve them on your own! There will be 10 problems in total and a 48-hour window to solve them. The problem indexing also features some April Fools elements, so you could say the problems are not sorted by difficulty. The contest starts on September 12 at 21:00 (UTC+3), right after Codeforces Round 1120 (Div. 1, Div. 2) finishes (well, almost right after, since the author is human too and needs a small break). Good luck and high ratings to everyone in the upcoming official round, and have fun!
