CF 105689B - Snake Years
The problem statement is missing, so there’s no way to reconstruct the actual task for “105689B - Snake Years” reliably. For a Codeforces editorial, even small details like input format or what “snake years” refers to completely determine the algorithm.

Solution
The problem statement is missing, so there’s no way to reconstruct the actual task for “105689B - Snake Years” reliably.
For a Codeforces editorial, even small details like input format or what “snake years” refers to completely determine the algorithm. If I guess, I would almost certainly end up explaining the wrong problem.
Paste the full statement (or even just the input/output description plus constraints), and I’ll write the complete editorial in the exact format you specified.
