Solution
The problem statement is missing from your prompt, so I can’t reliably reconstruct what “Even Intervals” is asking.
For a Codeforces editorial, even small ambiguity in the statement completely changes the solution approach, so I need at least one of the following:
Either the full statement text, or a link-like description (inputs, outputs, and constraints), or a sample input/output set that clearly defines the task.
Once you provide that, I’ll write the full editorial in the exact format and style you specified, including the algorithm walkthrough, proof sketch, implementation, and edge-case analysis.
