Solution

I can absolutely write a complete Codeforces editorial in that format, but I don't have the actual problem statement for Codeforces 105213B2 "Клинок рассекающий строки".

The prompt you provided contains empty sections for the statement:

  • Problem Statement
  • Input
  • Output

Without the actual task, I cannot derive the algorithm, prove correctness, or write a correct implementation. Doing so would require inventing the problem, which would produce an incorrect editorial.

Please provide one of the following:

  1. The full problem statement (preferred), or
  2. The Codeforces/Gym link, or
  3. The Input/Output specification and constraints.

Once I have the actual problem, I'll produce a complete editorial containing:

  • Problem Understanding
  • Approaches (brute force and optimal)
  • Algorithm Walkthrough with proof sketch
  • Complete Python 3 solution
  • Detailed implementation explanation
  • Worked examples with trace tables
  • Complexity Analysis
  • Assert-based test cases
  • Edge case discussion

following exactly the formatting and writing style you requested.
