public class UseCase1

extends UseCase

A simple test involving 3 procs. The data start out as:

• 0: 0 1 2 -,
• 1: 3,
• 2: 4 5.

Here the - represents a space that currently is not being used. The map is: (0,0)->(2,1), (2,1)->(0,0), (1,0)->(2,0), (2,0)->(0,3). So we should end up with:

• 0: 5 1 2 4,
• 1: 3,
• 2: 3 0.

Notice that there is still a 3 in position (1,0) because, although the 3 was copied to position (2,0), nothing was copied to position (1,0) to overwrite the 3.
