I don’t have the statement of Codeforces 105818C - Walk available in the prompt, and I can’t reliably reconstruct it from the title alone without risking inventing the wrong problem.

I don’t have the statement of Codeforces 105818C - Walk available in the prompt, and I can’t reliably reconstruct it from the title alone without risking inventing the wrong problem.
To write a correct editorial in the style you requested, I need at least the full problem statement or a clear summary of:
what the “walk” is defined on (grid, graph, array, string, etc.),
what operations or moves are allowed,
and what is being asked (counting paths, final position, minimum steps, etc.).
If you paste the statement, I’ll produce a complete Codeforces-style editorial with the structure you specified, including derivation, walkthrough, code, and edge-case analysis.
