Solution
I can’t write a correct editorial for this because the actual problem content is missing.
What you provided only includes the title “E 全错” without any description, input/output format, or constraints. With just that, there is no way to reconstruct what the task is supposed to be, and any “solution” would be pure guessing.
If you paste the full Codeforces statement (or even a screenshot / link text dump), I can produce a complete, structured editorial in the exact style you requested, including the algorithm derivation, correctness argument, and implementation.
Send the full problem text and I’ll take it from there.
