CF 102772G - Урок математики

I can't write a correct editorial for this problem because the actual problem statement is missing. The prompt only includes the title, "Codeforces 102772G - Урок математики", while the Problem Statement, Input, and Output sections are empty.

Solution

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

The prompt only includes the title, "Codeforces 102772G - Урок математики", while the Problem Statement, Input, and Output sections are empty. Without the statement, I do not know:

  • what the task is asking,
  • what the input format is,
  • what the output should be,
  • the constraints,
  • whether there are multiple test cases,
  • or what algorithm is required.

A complete editorial requires deriving and proving the solution for the actual problem, and I should not invent the problem or its algorithm.

Please provide either:

  1. the full problem statement (preferred), or
  2. a Codeforces link to the problem, or
  3. the input/output specification and constraints.

Once I have that, I'll produce the complete editorial with all the requested sections:

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

following your requested style and formatting exactly.
