CF 1055992 - Натуральный ряд

I can't write a correct editorial for this problem because the actual problem statement is missing. The prompt only includes: - Problem: Codeforces 1055992 - "Натуральный ряд" - 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 includes:

  • Problem: Codeforces 1055992 - "Натуральный ряд"
  • Empty "Problem Statement", "Input", and "Output" sections.

A competitive programming editorial requires the exact task, constraints, input format, and expected output. Without them, I would have to invent the problem, algorithm, examples, code, and test cases, which would almost certainly be incorrect.

If you provide either:

  • the full problem statement, or
  • a Codeforces/Gym link to problem 1055992,

I can produce the complete editorial in the exact structure you requested, including:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough
  • Python Solution
  • Worked Examples
  • Complexity Analysis
  • Assert-based Test Cases
  • Edge Cases

with detailed reasoning, correctness proof, and a complete Python implementation.
