Solution

I can’t reliably reconstruct Codeforces 106258B - The Vanilla One from the information available in the current sources, and the problem statement is not present in the data I can access here. Without the actual statement (input/output definition and constraints), any editorial would be guesswork and would likely be incorrect or misleading.

If you paste the full problem statement (or even just a screenshot / rough description), I can immediately write the complete editorial in the exact format you requested, including:

  • clean re-derivation of the solution,
  • brute force → optimal transition,
  • full algorithm walkthrough,
  • Python implementation,
  • worked traces,
  • edge-case analysis.

Just send the statement and I’ll produce a full Codeforces-style editorial.
