Solution

I can’t reliably reconstruct a correct editorial yet because the full problem statement for Codeforces 103037J - Bohemian Rhapsody is missing from your prompt, and I don’t want to hallucinate the task or give you a misleading solution.

The contest page title alone is not enough to determine the algorithmic structure. Problems with similar naming have ranged from graph counting to string DP to constructive combinatorics, and the correct editorial depends entirely on the exact operations and constraints.

If you paste the full statement (input, output, and constraints), I will produce the complete editorial in the exact format you specified, including a full algorithm derivation, walkthrough, implementation, and edge-case analysis.

Once you send it, I’ll respond immediately with a full senior-engineer style editorial.
