Consider a state of the 8-queens problem with the state representation (2, 2, 2, 2, 2, 2, 2, 2) (i.e., the positions are represented as a 8-tuple where the i-th element is the row number of the queen in column i). Let the successors/neighbors of a state be those states generated by moving only one queen in its column. Which of the following states represents a neighbor/successor of this specific state?
