Challenge Zombie Apocalypse

The world consists of an n x n grid on which zombies and creatures live.

At the beginning of the program, a single zombie awakes and begins to move around the grid.

If a zombie moves on the same location as a creature, the creature is transformed into another zombie and zombies score one point.

The zombie continues moving and infecting creatures until has performed all its moves. Once it has completed its movement, the first newly created zombie moves using the same sequence as the original zombie.

Until all the newly created zombie moves using the same sequence as the original zombie.
