Solution

I don't have enough information to write a correct editorial for this problem because the prompt does not include the actual problem statement. The title, "Codeforces 102697006 - Distance", is not sufficient to reconstruct the task, input format, constraints, or required algorithm.

Please provide one of the following:

  1. The full problem statement, including the input, output, and constraints.
  2. The Codeforces problem link.
  3. The exact contest and problem letter (for example, "Codeforces Round ###, Problem C - Distance").

Once I have the actual problem, I can produce the complete editorial with all of the requested sections, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough with correctness proof
  • Complete Python 3 solution using fast I/O
  • Detailed code explanation
  • Worked examples with state tables
  • Complexity Analysis
  • Assert-based test cases
  • Edge case analysis

Without the problem statement, any algorithm, code, complexity analysis, examples, or test cases would be speculative and could be incorrect.
