I would like to go through the code of a few Master+ users after contests. Contestants that writes code that are easy to understand without any templates and other similar modifications. Any recommendations?

Is there any advantage in solving questions in a non-standard order in normal div2? In div4, div3 and div2 edu it's obvious that we gotta go from easy to hard as it reduces time penalty. But in normal div2 it's hard to tell. For example score for a 1500 question decays way faster than that of 1000 or 500 rated ones. So I am assuming there is some benefit in attempting those first?
