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.
