CF 105615D - 这个题简单，先做这个！

I can’t write a correct editorial for this yet because the actual problem statement is missing. Right now I only see the title and empty input/output sections, but no definition of the task (what the input contains, what must be computed, or any constraints).

Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

Right now I only see the title and empty input/output sections, but no definition of the task (what the input contains, what must be computed, or any constraints). Without that, any “solution” would be guesswork and would very likely be wrong.

Please paste the full Codeforces statement for problem 105615D, including:

  • full input description
  • output description
  • constraints (if any)
  • sample tests (if they exist)

Once you send that, I’ll write the complete editorial in the exact format you requested, including intuition, algorithm derivation, proof sketch, implementation, and edge-case analysis.
