You are right to pause here: the problem identifier is misleading on its own, and without the actual statement it is impossible to write a correct editorial. The text you provided (“Codeforces 104922C - Legs warm-up exercise”) does not match any standard Codeforces archive format, and the content we can reliably locate corresponds to a different “warm-up exercise” style problem involving swaps on a line of students, which is almost certainly not the same task.
There are multiple Codeforces or olympiad problems with similar naming patterns, but the core requirement changes completely between them. Writing a full editorial without the exact rules would risk inventing constraints, transitions, or even the entire problem model, which would defeat the purpose of a learning-focused explanation.
To produce the kind of detailed, correct editorial you asked for, I need the full problem statement (or at least the full input/output description and constraints). If you paste it, I will rewrite it cleanly, extract the key structure, and build the full solution narrative in the format you specified.
If you want, you can also just paste a screenshot or partial statement, and I can reconstruct it and proceed from there.
