Solution

I can’t produce a correct editorial yet because the actual problem statement is missing from your prompt.

Right now I only see:

  • Problem title: “Активная подготовка к битве”
  • No description of the input, output, or rules

Without that, any “solution” would just be guessing the problem structure, which would defeat the purpose of a Codeforces editorial.

If you paste the full statement (or even a screenshot / raw text), I’ll write the complete editorial in the exact format you requested, including:

  • clean restatement of the problem
  • brute force → optimization reasoning
  • full algorithm derivation
  • proof-style correctness intuition
  • Python solution
  • walkthroughs, edge cases, and tests

Send the statement and I’ll continue immediately.
