This problem https://mirror.codeforces.com/contest/285/problem/B says "Consider all glasses are moving simultaneously during one shuffling operation.".
I don't understand how simultaneously makes sense, I solved the problem assuming one shuffling operation means moving the glasses in sequence* but I was just wondering if there is something I misunderstood.
* "if glass at position 1 goes from 1 to 2 and glass at position 2 goes from 2 to 3 then if marble was in glass at position 1 it ends up in glass at position 3" was my assumption.
Thank you for your help.

No, this isn't wrong. It means all glasses move in one moment
