Solution

We are missing the actual statement of Codeforces 105859C - Blaster the Daredevil, and that problem ID does not correspond to a publicly indexed standard Codeforces problem in the usual archive format. Without the statement, any full editorial (especially one with correctness arguments, edge cases, and worked examples) would be forced guesswork, which would defeat the purpose of a serious competitive programming explanation.

If you paste the problem statement (or even a screenshot / paraphrased version), I can produce the full editorial exactly in the style you requested: derivation from brute force, insight, algorithm, proof sketch, implementation details, and thorough traces.

Send the statement and I’ll take it from there.
