CF 1055995 - Геометрическая игра на планшете

I can't write a correct editorial for this problem because the actual problem statement is missing. The prompt only contains the title, "Codeforces 1055995 - Геометрическая игра на планшете", with empty Problem Statement, Input, and Output sections.

Solution

I can't write a correct editorial for this problem because the actual problem statement is missing.

The prompt only contains the title, "Codeforces 1055995 - Геометрическая игра на планшете", with empty Problem Statement, Input, and Output sections. A search also does not surface this Gym problem or its statement, so I cannot reconstruct the algorithm reliably.

A complete editorial requires the exact specification, including:

  • what the input represents,
  • what must be computed,
  • the constraints,
  • the required output,
  • and any sample tests.

Without those, I would have to invent the problem, which would make the editorial, proof, algorithm, and Python solution incorrect.

If you paste the full problem statement (or provide the Gym link or the original Russian text), I'll produce a complete editorial following your requested structure, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough
  • Correctness proof
  • Complete Python 3 solution
  • Worked examples
  • Complexity analysis
  • Assert-based test suite
  • Edge case discussion

all in the exact style and formatting you requested.
