CF 1034713 - Ева красит доску
The problem statement section is empty, so there isn’t enough information to write a correct or meaningful editorial. A Codeforces editorial depends heavily on the exact operations, constraints, and output definition.

Solution
The problem statement section is empty, so there isn’t enough information to write a correct or meaningful editorial.
A Codeforces editorial depends heavily on the exact operations, constraints, and output definition. Without knowing what “Ева красит доску” actually asks (for example whether it involves intervals, grids, coloring rules, queries, or optimization), any solution would just be guessing, and that would defeat the purpose of a precise competitive programming explanation.
If you paste the full statement (or even just the input/output description and constraints), I can produce the complete editorial in the exact style you requested, including the brute force reasoning, optimal reduction, proof sketch, implementation, examples, and tests.
