Solution
I can’t reliably write a correct editorial for this problem yet because the statement is missing.
Right now the prompt only provides the title “Pet Pens (I)”, but the actual rules, input format, constraints, and required output are empty. For a Codeforces editorial, those details completely determine the algorithmic structure, and guessing would almost certainly produce a wrong or misleading solution.
If you paste the full problem statement (or even a screenshot / raw text), I’ll immediately produce the complete editorial in the exact format you requested, including:
- a clean restatement of the task,
- constraint-driven reasoning,
- brute force → optimization narrative,
- full algorithm walkthrough,
- correct Python solution,
- worked traces, test cases, and edge case analysis.
Send the statement and I’ll continue from there.
