Solution
The problem statement is missing, so I can’t reconstruct the solution or write a correct editorial yet.
Codeforces problem IDs alone aren’t enough because multiple problems (especially from unofficial or Gym rounds like 103115F) don’t have reliably accessible or unique public statements in context.
Please paste the full problem statement, including input/output format and constraints. Once you do, I’ll produce the complete editorial in the exact structure you specified, with a full derivation, algorithm walkthrough, proof sketch, code, and tests.
