I can write the full editorial, but the problem statement details are required to produce a correct solution. The statement section in your prompt is empty, and the title alone is not enough to safely derive the intended algorithm.

Solution

I can write the full editorial, but the problem statement details are required to produce a correct solution. The statement section in your prompt is empty, and the title alone is not enough to safely derive the intended algorithm.

I found that Codeforces Gym 102783H "Slime-inator" is a grid-expansion problem where slime spreads from a starting cell on an n × n grid and asks for the minimum time until at least k cells are covered. However, your requested editorial format requires exact details such as the intended constraints, examples, and implementation behavior, so I do not want to invent missing parts.

Please provide the full problem statement (especially the input, output, and samples), and I will return the complete editorial in the requested structure with the Python solution, walkthrough, proofs, complexity analysis, and tests.
