Solution

I don’t have the actual problem statement for Codeforces 102891G - Silver Fences in your message, and without it I can’t safely reconstruct the solution or write a correct editorial.

If I try to proceed anyway, I’d be guessing the entire problem structure, which would almost certainly produce a wrong or irrelevant editorial.

Please paste the full problem statement (input/output + constraints if available). Once you do, I’ll write the complete Codeforces-style editorial exactly in the format you specified, including the algorithm walkthrough, proofs, code, and test cases.
