Solution

The statement for Codeforces 104830H (“Ore Excavation”) is not included in the prompt, so there is no way to reconstruct the actual task, constraints, or required algorithm safely.

Right now we only have the title and empty input/output sections. Any attempt to write a full editorial would require guessing the problem type, which would very likely produce an incorrect solution and misleading reasoning.

If you paste the full problem statement (or even a screenshot / raw text), I can produce the complete Codeforces-style editorial in the exact format you requested, including brute force reasoning, optimal insight, proofs, code, and edge case traces.
