Solution

I can write the full Codeforces-style editorial, but I’m missing the actual problem statement for 105424G - “Прогрессивный NoSQL”.

Right now I only have the title, so any attempt to reconstruct the task would be guesswork, and that would produce a misleading solution and incorrect complexity analysis.

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

  • full re-derivation of the solution
  • brute force → optimized transition
  • correctness argument
  • step-by-step algorithm walkthrough
  • Python implementation
  • traces, tests, and edge cases

Send it over and I’ll get started immediately.
