CF 104162D - Зима в городе К

I can’t write a correct Codeforces editorial for this yet because the actual problem statement (input, output, and rules) is missing. Right now I only know the title “104162D - Зима в городе К”, but that isn’t enough to reconstruct the task reliably.

Solution

I can’t write a correct Codeforces editorial for this yet because the actual problem statement (input, output, and rules) is missing.

Right now I only know the title “104162D - Зима в городе К”, but that isn’t enough to reconstruct the task reliably. Any attempt to infer it would likely invent constraints or even the core problem incorrectly, which would break the editorial completely.

Paste the full statement (or even a screenshot / raw text), and I’ll turn it into a complete, structured editorial in the exact style you specified, including approaches, walkthrough, proofs, code, and tests.
