Solution
I cannot safely reconstruct Codeforces 106056B “Path Planning” from reliable sources in a way that would let me write a correct editorial. The problem ID does not correspond to a standard publicly indexed Codeforces statement in the usual archive, and the available scraped references are unrelated or incomplete fragments. Writing a full solution editorial under these conditions would risk inventing problem details, which would defeat the purpose of a technical explanation.
If you paste the actual statement (or even just the key rules, constraints, and sample I/O), I can produce exactly the kind of deep, senior-level editorial you asked for, including a full derivation, algorithm walkthrough, and implementation.
To make this easy, here is what I need in minimal form:
The grid or graph description, allowed moves, objective, and constraints. Even a screenshot or rough paraphrase is enough.
Once you send that, I’ll reconstruct the full reasoning and write the complete editorial in the format you specified.
