Solution

I could not reliably recover the actual statement of Codeforces Gym 106260K from available sources. The title "调和级数求和" only indicates a harmonic-series summation problem, but the input format, required output, constraints, and exact quantity to compute are missing.

To write a correct editorial, I need the full problem statement, or at least:

Once you provide the statement, I can produce the complete editorial in the exact format you requested, including:

Problem Understanding
