Hello Codeforces community,

We are looking for multiple problems of varied difficulty, but in particular hard and very hard problems (similar to Codeforces D/E/F Div. 1). We don't require the problems to have the same author, but we will prioritise authors with multiple problems, especially those who have at least one hard in their set. The budget (per problem) is:

• extra hard: $400
• hard: $300
• medium: $200
• easy: $125

Please send an email with the statement and solution explanation at andrei@csacademy.com. Feel free to email us for any other additional info.

Cheers,

The CS Academy team
