Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

“Codeforces 102980C - Кибер-взлом” (Cyber-hack) isn’t included in your prompt, and I shouldn’t guess the task since even small misinterpretations would completely change the solution, constraints, and algorithm.

Please paste the full problem statement (or a link + text of input/output and constraints). Once you do, I’ll produce a complete Codeforces-style editorial in exactly the format you specified, including:

  • Proper problem restatement
  • Naive → optimal transition reasoning
  • Full algorithm walkthrough with invariants
  • Correct Python solution
  • Worked traces and edge-case analysis
  • Assert-based test suite

Send the statement and I’ll proceed.
