java n-puzzle

The n-puzzle is a classic sliding puzzle game that consists of a frame of numbered square tiles in random order with one tile missing. The objective of the puzzle is to arrange the tiles in order by sliding them around the frame, with the empty space at the bottom right. The puzzle can be played with any number of tiles, but the most common version is the 8-puzzle.

Here is an example of a 3x3 8-puzzle:

1 2 3
4 5 6
7 8

To solve the puzzle, the player must slide the tiles around the frame to form the following configuration:

1 2 3
4 5 6
7 8 9

The difficulty of the puzzle increases with the number of tiles, as there are more possible configurations to solve.

In Java, the n-puzzle can be implemented using a two-dimensional array to represent the game board, and various algorithms such as A* or DFS can be used to solve the puzzle. The implementation can also include features such as a graphical user interface, timer, and score tracking for competitive play.
