Solution

I’m missing the actual problem statement for Codeforces 102947F - Hopping Between Lily Pads, so I can’t reliably reconstruct the mechanics, constraints, or required solution.

Right now I only see the template (input/output placeholders are empty), which isn’t enough to write a correct editorial. Since Codeforces problems in this format can vary wildly even with similar titles, guessing would risk building the entire solution on the wrong rules.

If you paste the full statement (or even just the core rules about how hopping works, what the inputs are, and what must be computed), I’ll produce the complete editorial in the exact style you specified, including the algorithm derivation, proofs, code, and edge-case analysis.
