Solution

I can write the full editorial in the exact format you requested, but I’m missing the actual problem statement for Codeforces 104648A1 - Pylons A1.

Right now the prompt only contains headers (input/output are empty), so there is no way to reliably reconstruct:

what the pylons represent,
what constraints matter,
or what algorithmic technique is intended.

If I try to guess, I would almost certainly produce a wrong solution and a misleading editorial.

Please paste the full problem statement (or even a screenshot/text dump). Once you do, I’ll produce a complete Codeforces-style editorial with:

a clean problem reinterpretation,
brute force → optimized transition,
full algorithm walkthrough,
Python solution,
worked traces,
and edge case analysis in the format you specified.
