Solution

I can absolutely write the editorial, but I don't have enough information for this specific problem.

The prompt refers to Codeforces 105664C - Boredom, but the problem statement, input format, and output format are empty. A web search also does not identify a Gym problem with that exact ID and title, so I cannot reconstruct the task reliably.

A complete editorial requires the actual problem details so that I can derive and explain the correct algorithm, prove its correctness, provide an implementation, construct worked examples, and write valid test cases. Without the statement, I would have to invent the problem, which would almost certainly produce an incorrect editorial.

Please provide one of the following:

  1. The full problem statement for Codeforces 105664C - Boredom.
  2. A link to the problem.
  3. A PDF or screenshot of the statement.

Once I have the statement, I'll produce the complete editorial in the exact structure you requested, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough with proof sketch
  • Complete Python 3 solution
  • Detailed implementation explanation
  • Worked Examples with trace tables
  • Complexity Analysis
  • Assert-based Test Cases
  • Edge Cases

while following all of your formatting and style requirements.
