Solution

The statement you provided is incomplete, so there isn’t enough information to reconstruct what Codeforces 106289F - Harvest Statistics is actually asking.

Right now we only have the problem title, but the crucial parts are missing: what the input represents, what needs to be computed, and any constraints. Without those, any editorial would be guesswork and would very likely describe the wrong problem.

If you paste the full statement (or even a screenshot or raw text), I can write the complete Codeforces-style editorial exactly in the format you specified, including the algorithm walkthrough, proof, code, and edge-case analysis.
