Representation of the Frame

• We need 16 variables, one to represent the tile at each position in the frame.

• We could use the declaration:

int[] puz = new int[16];

to get variables puz[0], . . ., puz[15], but this is unwieldy and unnatural.

• Rule of Thumb. Unless there is a compelling reason algorithmic reason to do otherwise, use data that is structured similarly to the physical device being simulated.

• We use a two-dimensional array.
