Representation of the Tiles

• How should the tiles be represented?

• We need 15 values to represent the tiles and one to represent the blank?

// Use 1..15 for the tiles and 0 for blank.

final int Blank = 0;

or

// Use 1..15 for the tiles and 16 for blank.

final int Blank = 16;

• Rule of Thumb. Choose uniform representations if at all possible
