CF 106069L - Land of the Golden Butterflies

I can write the full editorial in that format, but I’m missing the actual problem details. The statement section in your prompt is empty, and I couldn’t reliably identify the problem from only “Codeforces 106069L - Land of the Golden Butterflies”.

Solution

I can write the full editorial in that format, but I’m missing the actual problem details. The statement section in your prompt is empty, and I couldn’t reliably identify the problem from only “Codeforces 106069L - Land of the Golden Butterflies”.

Please paste the full problem statement (or the link to the problem page), including the input/output format and constraints. Once I have it, I’ll produce the complete editorial with the requested sections, proof, complexity analysis, Python solution, examples, tests, and edge cases.
