On Codechef, I see difficulty ranging from cakewalk, simple, easy, easy-medium, medium, medium-hard, and hard on the editorials. Can anyone provide me a loose mapping of the these difficulties on Codeforces rating?
Providing some form of data such as the rating of the problems you practice on here, compared to the difficulty you practice on Codechef would be helpful as well.
Find people who use both Codechef and Codeforces, check their time to solve problems of each difficulty, and let us know what's the mapping.
