Solution

I can certainly write a complete editorial, but I do not have enough information to do so correctly from the title alone.

The Gym problem page for Codeforces Gym 105628H - Hop, Skip, Jump! is available, but it is a constructive output problem whose solution depends on the exact reasoning and construction. The page only provides the statement, not the intended algorithm or proof.

A high quality editorial requires deriving and proving the construction. I can't reliably invent that algorithm, because it would risk producing an incorrect editorial and incorrect reference solution.

If you provide either:

  1. the full problem statement (or simply paste it),
  2. the official editorial,
  3. or your accepted solution,

I can produce exactly the editorial format you requested, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough with proof
  • Complete Python solution
  • Worked Examples
  • Complexity Analysis
  • Assert-based Test Cases
  • Edge Cases

following all of your formatting and style requirements.
