Solution

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

The statement section in your prompt is empty, and I could not reliably identify the problem details for Codeforces 106409I - Daniel Saves Yash from the available information. Without knowing the input format, output requirements, constraints, and examples, I would have to invent the algorithm, which would make the editorial misleading.

Please paste the full problem statement (including Input, Output, Constraints, and Samples), and I will produce the complete editorial with the requested sections, proof explanation, Python solution, walkthroughs, complexity analysis, and tests.
