CF 103535K - Yiwen with Formula

The problem statement is missing, so there isn’t enough information to derive the solution, constraints, or even what the task is asking. Right now we only have the title “Yiwen with Formula”, but no description of inputs, outputs, or rules.

Solution

The problem statement is missing, so there isn’t enough information to derive the solution, constraints, or even what the task is asking.

Right now we only have the title “Yiwen with Formula”, but no description of inputs, outputs, or rules. Without that, any editorial would be pure guessing, which would defeat the purpose of a Codeforces-style writeup.

If you paste the full statement (or even a screenshot transcription), I can produce the complete editorial in the exact format you specified, including the algorithm derivation, proof sketch, implementation, and test cases.
