CF 106507B - Flower Ring
I can write the editorial, but I’m missing the actual problem details. The prompt only includes the title “Codeforces 106507B - Flower Ring” and empty sections for the statement/input/output, and I can’t reliably reconstruct the intended problem from the title alone.

Solution
I can write the editorial, but I’m missing the actual problem details. The prompt only includes the title “Codeforces 106507B - Flower Ring” and empty sections for the statement/input/output, and I can’t reliably reconstruct the intended problem from the title alone.
Please paste the full problem statement (including input/output and constraints), and I’ll produce the complete editorial in the requested format with the algorithm, proof, Python solution, traces, tests, and edge cases.
