CF 102900G - Fibonacci
The problem statement is missing from your prompt, so I don’t actually know what Codeforces 102900G - Fibonacci is asking. Right now I only see the title, but no definition of the input, output, or task.

Solution
The problem statement is missing from your prompt, so I don’t actually know what Codeforces 102900G - Fibonacci is asking.
Right now I only see the title, but no definition of the input, output, or task. Without that, any editorial would be guesswork, and for competitive programming that would produce a completely incorrect solution.
If you paste the full statement (or even just the core description and constraints), I can immediately produce the full editorial in the exact format you requested, including:
- clear restatement of the problem in my own words
- brute force and optimized transition
- full proof-style reasoning
- Python implementation
- worked traces and edge cases
Send the statement and I’ll write the complete editorial.
