Solution
I can’t write a correct editorial yet because the actual problem statement for Codeforces 103647A - Night Nesting is missing from your prompt.
Right now there is no description of:
- what the input represents,
- what the output should compute,
- or even the task structure (arrays, graphs, strings, etc.).
Without that, any “solution” would just be guessing, and that would defeat the purpose of a Codeforces editorial.
If you paste the full problem statement (or even a screenshot / raw text), I can immediately produce a complete, properly structured editorial in the exact style you requested, including:
- a real intuition chain from brute force to optimal,
- correctness reasoning,
- implementation,
- worked traces,
- and edge-case analysis.
Send the statement and I’ll continue from there.
