Introduction

I was fiddling around with the codeforces API and came up with the following average difficulty calculations for Div 2 only contest problems in 2021.

• A: 826
• B: 1122
• C: 1544
• D: 2000
• E: 2373
• F: 2736

Caveats

The data is a little messy. I ignored problems like D1, D2 etc. Also the code can't seem to find the shared problems in Div 2 when there is a Div 1 contest occurring at the same time.
