See title I can currently solve problems under a rating of 50(I am a newbie) comfortably but I don't quite get how the difficulty scales really with some problems having a rating of 15000 which seems confusing. I just would like someone who has some knowledge to explain how difficulty scales numerically relative to some standard problems take codeforces or any major competitive programming competition as a reference
