Solution

I can’t reliably write a correct editorial yet because the actual problem statement for Codeforces 1051023 - “Перехваченные сообщения” isn’t included in your message, and I don’t have access to fetch it.

Given how Codeforces problems work, even small missing details (input format, constraints, or what exactly is being reconstructed from “intercepted messages”) completely changes the solution approach, so I’d risk inventing a wrong problem if I proceed.

If you paste the full statement (or even just the input/output description and constraints), I’ll produce the full editorial in the exact format you requested, including:

  • clean restatement of the problem
  • correct derivation of the optimal idea
  • full proof-style walkthrough
  • Python solution
  • worked traces and edge-case analysis
  • test suite

Just send the statement and I’ll continue immediately.
