I can’t reliably write a correct editorial for this yet because the actual problem statement (what operations are allowed, what input/output mean, constraints, etc.) is missing from the prompt.

Solution

I can’t reliably write a correct editorial for this yet because the actual problem statement (what operations are allowed, what input/output mean, constraints, etc.) is missing from the prompt.

“Codeforces 104003G - William and Spaceport” isn’t enough to reconstruct the task without guessing, and guessing would almost certainly produce a wrong solution and misleading reasoning.

If you paste the full statement (or even a screenshot/text dump), I’ll produce the complete editorial in the exact style you requested, including a proper derivation, optimal approach, Python solution, traces, and edge-case analysis.
