Any live cell with fewer than two live neighbors dies, as if by underpopulation.

generation x (n < 2)

generation x + 1

Any live cell with two or three live neighbors lives on to the next generation.

generation x (n = 2,3)

generation x + 1

Any live cell with more than three live neighbors dies, as if by overpopulation.

generation x (n > 3)

generation x + 1

Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.

generation x (n = 3)

generation x + 1

Consists of:

1. Tests Pass
2. Expresses Intent
