Solution
The problem statement for Codeforces 105299F “Magic Path” is missing from your prompt, so I don’t have the actual rules of the movement, grid/graph structure, or what needs to be computed.
Without that, any full editorial would be guesswork, and for this format that would almost certainly produce a wrong solution explanation and incorrect code.
If you paste the full statement (or even a screenshot / raw text), I’ll write the complete editorial in the exact structure you specified, including:
A clean restatement of the problem in graph or grid terms, a derivation from brute force to optimal solution, a precise algorithm walkthrough with invariants, full Python implementation, worked examples, complexity analysis, test cases, and edge case traces.
Send the statement and I’ll proceed.
