CF 106491B - Право на ошибку

I can write the full editorial in the requested format, but I need the actual problem statement first. The statement section in your prompt is empty, and I could not reliably identify Codeforces 106491B “Право на ошибку” from the available information.

Solution

I can write the full editorial in the requested format, but I need the actual problem statement first.

The statement section in your prompt is empty, and I could not reliably identify Codeforces 106491B “Право на ошибку” from the available information. Without the input format, output requirements, and the exact task, writing an algorithm explanation and Python solution would risk inventing a problem.

Please paste the full statement (including examples if available), and I’ll produce the complete editorial with all requested sections and formatting.
