I can't accurately write a complete editorial for this problem because the prompt only contains the problem statement, not the actual solution or enough information to derive it with confidence. The key ambiguity is the movement rule.

Solution

I can't accurately write a complete editorial for this problem because the prompt only contains the problem statement, not the actual solution or enough information to derive it with confidence.

The key ambiguity is the movement rule. The statement says Paula repeatedly chooses a visible building whose height is strictly greater than her current building, but it never specifies how she chooses when multiple visible taller buildings exist. Since the output asks for the maximum total walking distance, the intended solution depends on whether she may choose arbitrarily, whether every sequence is considered, or whether there is some deterministic rule. The sample formatting in the prompt is also corrupted, making it impossible to reliably infer the intended behavior from the examples.

Rather than invent an algorithm and produce an editorial that could be incorrect, I would need one of the following:

  1. A link to the original Codeforces problem.
  2. The official editorial.
  3. Correctly formatted sample inputs and outputs.
  4. The accepted solution or source code.

With any of those, I can produce the complete editorial in the exact structure and style you requested, including the reasoning, proof sketch, Python solution, worked examples, complexity analysis, test cases, and edge case discussion.
