CF 1381E - Origami

I can't write a correct editorial for Codeforces 1381E from the information provided here because the actual problem statement, input format, and constraints are missing. Codeforces 1381E is a 3300-rated geometry/math problem, and the solution is highly problem-specific.

Solution

I can't write a correct editorial for Codeforces 1381E from the information provided here because the actual problem statement, input format, and constraints are missing.

Codeforces 1381E is a 3300-rated geometry/math problem, and the solution is highly problem-specific. Producing a full editorial with algorithm, proof, implementation, worked examples, complexity analysis, and test cases without the statement would require inventing the problem details, which would almost certainly be incorrect.

Please provide one of the following:

  1. The full text of the problem statement, or
  2. A link to the problem statement, or
  3. The input/output format and constraints, plus the sample tests.

Once you provide the statement, I'll write the complete editorial in the exact structure you requested:

  • Problem Understanding
  • Approaches
  • Algorithm Walkthrough
  • Correctness Sketch
  • Full Python 3 Solution
  • Code Explanation
  • Worked Examples with tables
  • Complexity Analysis
  • Assert-based Test Cases
  • Edge Cases

and I will keep the style and formatting constraints exactly as specified.
