Solution

I can write the full Codeforces-style editorial, but the problem statement is missing from your prompt.

“Codeforces 1055272 - Добби и носки” isn’t enough on its own to reconstruct the task reliably, and guessing would risk producing a completely incorrect solution.

Please paste the full statement (or even a screenshot / raw text). Once you do, I’ll produce the complete editorial in the exact format you requested, including:

  • Clean restatement of the problem
  • Brute force → optimal transition
  • Full algorithm walkthrough
  • Verified Python solution
  • Worked traces, complexity, and edge-case handling
