CF 105803A - ADN
I don’t have the actual statement of Codeforces 105803A - ADN in your prompt (it’s empty), so I can’t reliably reconstruct the problem or write a correct editorial without risking hallucination.

Solution
I don’t have the actual statement of Codeforces 105803A - ADN in your prompt (it’s empty), so I can’t reliably reconstruct the problem or write a correct editorial without risking hallucination.
If you paste the full problem statement (or even just input/output description and constraints), I’ll produce the complete editorial in the exact style you requested, including algorithm derivation, walkthrough, code, tests, and edge case analysis.
