CF 103678D - Бернард и кирпичная стена

I’m missing the actual problem statement for Codeforces 103678D - “Бернард и кирпичная стена” (the section is empty in your prompt), so I can’t reliably reconstruct the task or produce a correct editorial.

Solution

I’m missing the actual problem statement for Codeforces 103678D - “Бернард и кирпичная стена” (the section is empty in your prompt), so I can’t reliably reconstruct the task or produce a correct editorial.

To write the kind of detailed, correctness-focused walkthrough you want, I need at least:

  • full statement (or a link / paste)
  • input/output format
  • constraints
  • sample tests if available

Once you provide that, I’ll produce the complete editorial in the exact style you specified, including algorithm derivation, walkthrough, implementation, and edge-case analysis.
