Solution

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

Problem restatement and observations
Key idea / intuition
Proof of correctness
Algorithm
Complexity analysis
Implementation details
Reference C++17 solution (if desired)

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