Solution
I can’t write a correct editorial for this problem yet because the actual problem statement is missing from your prompt.
Right now I only see the title “Бернард и IQ ПФО”, but there is no description of:
what the input contains, what transformation or decision is required, or what the output should be. Without that, any “solution” would be guesswork, and for Codeforces editorials that would almost certainly be wrong.
If you paste the full statement (or even just the input/output description and constraints), I’ll produce the complete editorial in the exact format you requested, including a full algorithm walkthrough, proof sketch, Python solution, worked traces, and edge case analysis.
