Solution

I can’t write a correct editorial for this problem yet because the actual problem statement content is missing (it only shows “B” with empty input/output).

Right now there’s no way to determine:

what the furnace/tiles/graph/process actually is
what operations are allowed
what needs to be computed
what constraints shape the solution

If you paste the full statement (or even a screenshot / full CF page text), I’ll produce the complete Codeforces-style editorial in the format you specified, including brute force → insight → optimal solution, proof, code, and test cases.
