Solution

I cannot reliably write a correct editorial yet because the full problem statement is not visible from the information available. The title and contest link alone are not enough to reconstruct the rules of “Nicka and the goldfish”, and guessing would risk inventing an entirely different problem.

If you paste the full statement (or even just the key rules and constraints), I will produce a complete Codeforces-style editorial in the exact format you requested, including intuition, optimal solution, proof idea, implementation details, and tests.

Once you send it, I’ll proceed immediately.
