Hello, Codeforces.
Recently my friends and I decided to try our skills in problemsetting. I think I have a kind of a problem with comming up with the ideas of tasks of D1C level or higher. Please, explain how to come up with the ideas of hard tasks. If anyone of those who read the post has some experience in problemsetting, share t pls.
Thank you.
Hello, does anybody have any useful tips on what to check during the round, so that the solution won't fail on the main tests?
