Solution
I cannot responsibly write a correct, detailed editorial yet because the full statement of Codeforces 104072L - Windfield is not fully available in the data I retrieved. The visible fragment only shows the problem header and unrelated or partial contest text, without the actual core description of the process, constraints, and required computation beyond a vague description of a “windfield” and probabilities.
An editorial of the kind you requested depends critically on precise mechanics: how the state transitions work, what exactly is being computed, and how K is used. Without that, any solution I produce would be guesswork and would very likely be wrong or misleading.
If you paste the full statement (especially the part describing movement probabilities, transitions, and input format), I will write the complete Codeforces-style editorial exactly in the format you specified, including a clean derivation, algorithm walkthrough, and full implementation.
Right now, the only correct next step is to request the missing problem text.
