CF 105424A - Середина игры
I don’t have the actual statement of Codeforces 105424A (“Середина игры”) available in this context, and I can’t safely reconstruct it from the title alone without risking inventing details that don’t match the problem.

I don’t have the actual statement of Codeforces 105424A (“Середина игры”) available in this context, and I can’t safely reconstruct it from the title alone without risking inventing details that don’t match the problem.
To write a correct editorial in the style you requested, I need at least one of the following:
- Full problem statement, or
- A link plus confirmation of what the task asks, or
- Input/output description and constraints.
Once you provide that, I’ll produce a complete Codeforces-style editorial with the structure you specified (problem understanding, approaches, walkthrough, code, proofs, tests, edge cases).
