This post is on serious issue. Currently my level is DIV2-C,D (during contest i am mostly able to solve C and sometimes D) . Whenever i fail to solve any problem (say D) and i see editorial i am able to understand the solution very quickly most of the times .

But when i see solution(editorial) for problem E or F , sometimes i find difficult to understand the editorial itself ! Why ? Because most authors write solution in a way which can be only understood by person who is able to solve problems of that difficulty level most of the time .

But the problem is it becomes difficult for people to improve fast.They either do not upsolve or take days to figure out what editorial want's to say . Now some RED people might say that editorial don't explain fully or give proper details because they want YOU TO THINK . But editorial can be written by adding spoilers such that a person first tries on his own to understand and then if not able to he can read the spoiler .Please see following editorial written by T.M William Link .In difficult problems authors can explain the solution using an concrete example.I want such type of editorial on coding platforms.That is education ! First try on your own and if not able to succeed seek the help ! you can't keep figuring out whole life.

May be time is issue for writing good editorials .But quality > time .Take 1/2 day for releasing the tutorial but write them properly .

You can see past contests and observe that number of people who upsolve a problem (D/E/F) is proportional to the quality of editorial .Else people keep commenting to explain them properly in simple words etc .

I will also accept suggestions from people on how to read editorial properly .
