CF 105679E - A Symphony of Lights

I’m missing the actual problem content for “Codeforces 105679E - A Symphony of Lights”. Right now the statement sections (problem description, input, output) are empty, so there’s nothing concrete to base the editorial on.

Solution

I’m missing the actual problem content for “Codeforces 105679E - A Symphony of Lights”.

Right now the statement sections (problem description, input, output) are empty, so there’s nothing concrete to base the editorial on. For Codeforces editorials, even a small detail like whether this is a graph, string, or DP problem completely changes the solution approach, so I can’t safely reconstruct it.

Paste the full problem statement (or even just the key parts), and I’ll produce the complete editorial in the exact style you specified, including intuition, optimal derivation, walkthrough, complexity, and tests.
