Solution

I can absolutely write a full editorial in that format, but I don't have the actual problem.

The Gym problem Codeforces 105645B - Best Problem is not publicly retrievable from the information available to me, and your prompt contains an empty statement:

## Problem Statement

## Input

## Output

Without the problem statement, I cannot derive the algorithm, write a correct proof, produce a valid implementation, or construct accurate examples and test cases. Doing so would require inventing the problem, which would make the editorial incorrect.

If you provide either:

  1. the complete problem statement, or
  2. the contest link, or
  3. the input/output specification,

I'll produce the complete editorial exactly in the structure you requested, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough with proof sketch
  • Complete Python 3 solution
  • Code explanation
  • Worked examples with trace tables
  • Complexity analysis
  • Assert-based test cases
  • Edge case discussion

and I'll follow all of your requested style and formatting constraints.
