I can’t write a correct editorial for “Codeforces 105782B - Picture Perfect” because the actual problem statement is missing from your message.
Right now I only see the formatting scaffold (Input/Output sections are empty), so there’s no way to know what the task is, what the operations are, or what needs to be optimized.
Paste the full problem statement (or even a screenshot/text dump), and I’ll produce a complete Codeforces-style editorial exactly in the structure you requested.
