Some extremely difficult problems are displayed as *2100 or even lower. For example,
Obviously, these problems are too difficult for live contestants to solve, which misleads the difficulty algorithm and make it give wrong results. Today during my daily training, I randomly chose a *2100 problem(2276G) and failed to solve it within 2 hours. I felt disappointed and read the tutorial, only to find that I couldn't even understand it, and finally checked the standings and realized *2100 is just a mistake.
I think this should be solved. Maybe it's just a corner case of the difficulty algorithm.
