CF 105603B - Попасть в замок МакДафф

I can’t write a correct editorial for this problem yet because the actual problem statement is missing from your prompt. “Codeforces 105603B - Попасть в замок МакДафф” only gives the title, but no information about inputs, outputs, or rules.

Solution

I can’t write a correct editorial for this problem yet because the actual problem statement is missing from your prompt.

“Codeforces 105603B - Попасть в замок МакДафф” only gives the title, but no information about inputs, outputs, or rules. Any attempt to reconstruct the task would be guesswork, and that would defeat the purpose of a Codeforces editorial.

If you paste the full statement (or even a screenshot / link text), I’ll produce a complete senior-level editorial in exactly the format you specified, including the algorithm derivation, proof sketch, implementation details, and test suite.

Send the statement and I’ll continue from there.
