Solution

Sure. Please provide the Codeforces problem statement (or a link, title, and constraints), and I’ll write a detailed editorial in a competitive programming style.

I can structure it like:

Problem restatement
Key observations
Why the naive approach fails
Main idea / insight
Algorithm
Proof of correctness
Complexity analysis
Implementation details
Reference C++17 solution

I’ll keep it in the style of an official Codeforces editorial.
