Hello Codeforces community,
We are looking for 4 hard problems (the difficulty level should be around a Codeforces D/E Div. 1). We don't require the problems to have the same author, so if you only have one suitable problem that's fine with us, we'll use the first come- first served principle. The compensation budget for this project is $400/problem.
Please send an email with the statement and solution explanation at email@example.com. Feel free to contact Andrei for any other additional info.
