he 8-puzzle will be represented by a 3x3 list of lists positions where the empty box will be represented by the value 9, as shown below: [[9,1,3],[5,2,6],[4,7,8]] Possibility Solution: Only half of the initial positions of the 8-puzzle are solvable. There is a formula that allows to know from the beginning if you can solve the puzzle.To determine whether an 8-puzzle is solvable, for each square containing a value N is calculated how many numbers less than N there after the current cell. For example, to the initial status
