CF 106439N - Chapo Nahi Mili

I can write the full editorial in that format, but I do not have enough information about the problem itself. The statement section in your prompt is empty, and I could not reliably identify the problem from only “Codeforces 106439N - Chapo Nahi Mili”.

Solution

I can write the full editorial in that format, but I do not have enough information about the problem itself.

The statement section in your prompt is empty, and I could not reliably identify the problem from only “Codeforces 106439N - Chapo Nahi Mili”. I do not want to invent the problem model, constraints, algorithm, or code and give you an incorrect editorial.

Please paste the full problem statement (including input, output, constraints, and samples), and I will produce the complete editorial with all requested sections and a correct Python solution.
