Every time it takes me a while to find the tutorial for the problem that I can not solve， I have to find the corresponding post first. Why can't codeforces has an extra tab for a tutorial in Problem webpage?

For example, leetcode has a "solution" tab for each problem, and I believe it is convenient for users.

A couple of days before I have the purple name, and I am trying to do some practice in GYM by solving the problem with difficulty between 2000-2200. However, I found that I can always have a clear idea, but get confused in implementations which is really different when I solve a problem with difficulty below 2000. What can I do? Does that mean that 2000 is the limit of my ability?
