Solution
I can’t write a correct editorial for “Codeforces 105709C - Finchy Flying” because the actual problem statement is missing from your prompt.
Right now there is no description of: what Finchy is doing, what the input represents, what needs to be optimized or computed, or what constraints apply. Without that, any “solution” would be guesswork, and for Codeforces editorials that would almost certainly be wrong.
If you paste the full problem statement (or even a screenshot or partial text), I can produce a complete editorial in the exact style you requested, including:
- a clean restatement of the problem,
- brute force to optimal transition,
- full derivation of the key idea,
- implementation details in Python,
- worked traces,
- edge case analysis.
Send the statement and I’ll write the full walkthrough.
