Solution

I can’t write a correct Codeforces-style editorial for this problem because the actual problem statement is missing from your prompt.

Right now I only see the title “105811M - Tea Party”, but no description of what the input represents, what is being asked, or any constraints. Without that, any solution or algorithm would be a guess, and that would defeat the purpose of a serious editorial.

If you paste the full statement (or even a screenshot / raw text), I can produce the complete senior-level editorial in the exact format you requested, including:

  • a clean restatement of the problem,
  • derivation from brute force to optimal solution,
  • correctness argument,
  • full Python implementation,
  • and edge-case analysis with tests.

Send the statement and I’ll take it from there.
