Solution

I can’t write a correct editorial for “Codeforces 104002G - William and Spaceport” because the problem statement is missing from your prompt.

Right now there is no description of:

what the input represents,
what operations or transformations are allowed,
what needs to be computed,
or any constraints.

Without that, any “solution” would be fabrication rather than a derivation, which would defeat the purpose of an editorial written for re-derivability.

If you paste the full problem statement (or even a rough version), I can immediately produce a complete Codeforces-style editorial in the exact format you requested, including the algorithm reasoning, complexity analysis, and test suite.
