Solution

I can’t write a correct editorial yet because the actual problem statement (including input format, constraints, and what “Arranging Utensils” is asking) is missing from your prompt.

Right now I only know the title and that it is Codeforces 103031B, but there is no way to reconstruct:

what the objects are, what operations are allowed, what must be optimized, or even what the output represents.

If you paste the full statement (or even a screenshot/text dump), I’ll produce the complete editorial in the exact format you specified, including:

a full re-derivation of the solution,

brute force to optimal transition,

formal algorithm walkthrough,

proof sketch,

edge case analysis,

and tested reference implementation.

Send the statement and I’ll continue immediately.
