CF 106478B - Lost Cursor
I can write the full editorial, but I need the actual problem statement first. The prompt only gives the title “Codeforces 106478B - Lost Cursor” and leaves the Statement/Input/Output sections empty.

Solution
I can write the full editorial, but I need the actual problem statement first.
The prompt only gives the title “Codeforces 106478B - Lost Cursor” and leaves the Statement/Input/Output sections empty. I do not have enough information to determine the mechanics, constraints, samples, or the intended algorithm reliably. A problem title and ID alone are not sufficient because some Codeforces Gym problems are not indexed consistently.
Please paste the full problem statement (including constraints and samples), and I will produce the complete editorial in the requested format with the explanation, algorithm, Python solution, tests, and edge cases.
