Problem

Given a sequence of cube states represented as lists of three visible face labels [front, right, top], exactly one state is missing. Each next state is produced by rotating the same cube by a fixed operation. Return the missing state as a list of three labels.

Constraints

3 <= len(states) <= 10^4
Each known state is either null or a list of exactly 3 integers
Face labels are distinct integers from 1 to 6
Exactly one state is missing
The sequence follows repeated applications of one fixed cube rotation
