What could be the possible approach for the following problem using Python?
Stuart has some difficulty memorizing the small prime numbers. So, his computer science teacher has asked him to play with the following puzzle game frequently. The puzzle is a 3x3 board consisting of numbers from 1 to 9. The objective of the puzzle is to swap the tiles until the following final state is reached: 1 2 3 4 5 6 7 8 9 At each step, Stuart may swap two adjacent tiles if their sum is a prime number. Two tiles are considered adjacent if they have a common edge. Help Stuart to find the shortest number of steps needed to reach the goal state.
