Solution

I can’t write a correct editorial yet because the actual problem statement for “Codeforces 103256D - Sightseeing with Friends” is missing from your prompt.

Right now there is no definition of:

what the input represents (graph, array, tree, queries, etc.)
what operation or optimization is required
constraints (which determine the algorithm class)
required output behavior

Without that, any “solution” would be guesswork and very likely wrong.

Paste the full problem statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact format you specified.
