Solution

I can’t write a correct editorial yet because the problem statement for “Codeforces 104003H - William and will.i.am” is missing from your prompt.

Right now I don’t know what the input represents, what is being asked, or even the structure of the task, so any attempt to fill the sections would be guesswork and would very likely be wrong.

Paste the full statement (or even a screenshot/text dump), and I’ll produce the complete editorial in the exact format you specified, including the algorithm derivation, proof sketch, implementation, examples, and tests.
