Solution

I can absolutely write that editorial, but I don't have the actual problem statement for Codeforces 102621H "Platypus Puddles".

The prompt only contains empty sections for:

  • Problem Statement
  • Input
  • Output

A correct editorial requires the exact problem definition, constraints, input format, and expected output. Without those, I would have to invent the problem, which would lead to an incorrect algorithm, proof, implementation, examples, and test cases.

Please provide one of the following:

  1. The full problem statement for Codeforces 102621H - Platypus Puddles, or
  2. A link to the problem, or
  3. The PDF/HTML/text of the statement.

Once I have the statement, I'll produce a complete editorial including:

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

following all of your requested formatting and style requirements.
