CF 105254Z - Archaeological Recovery

I can’t write a correct Codeforces-style editorial for this yet because the actual problem statement is missing from your prompt. Right now I only see the title “Archaeological Recovery”, but no description of the task, input format, or output requirements.

Solution

I can’t write a correct Codeforces-style editorial for this yet because the actual problem statement is missing from your prompt.

Right now I only see the title “Archaeological Recovery”, but no description of the task, input format, or output requirements. Any attempt to proceed would require guessing the problem structure, which would almost certainly produce a misleading or incorrect editorial.

If you paste the full statement (or even just the core description and constraints), I can produce the complete senior-level editorial in the exact format you specified, including the derivation, correctness argument, and code.
