Solution

I’m missing the actual problem statement for Codeforces 103643C - Painting Fences (Easy Version), so I can’t reliably reconstruct the task or derive a correct solution.

This kind of editorial depends heavily on the exact operations on the fence, constraints, and what is being optimized or counted. Different “painting fences” problems on Codeforces Gym vary a lot (some are interval coloring, some are DP over segments, some involve greedy + sorting), and guessing would likely produce a completely wrong explanation and solution.

Please paste the full problem statement (or even just the core description plus input/output format and constraints). Once you do, I’ll write the complete editorial in the exact style you requested, including the walkthrough, proofs, and full Python solution.
