Solution
The statement for “Codeforces 106030K - 小 C 的神秘图形” is not actually included in what you provided. Right now there is no description of the input, output, or even what the “mysterious figure” is supposed to be, so there is no way to reconstruct the intended algorithm without guessing.
A correct editorial depends entirely on the missing parts: what structure is being built (grid, graph, geometry, string pattern, etc.), what operations are allowed, and what needs to be computed. With only the title and empty input/output sections, any solution would be speculative and very likely unrelated to the real problem.
If you paste the full statement (even a screenshot or raw text), I can write the complete Codeforces-style editorial in the format you specified, including the derivation, optimal approach, walkthrough, and proofs.
