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.
