1 In Programming Project 4.1, you implemented the Sparse Life Grid ADT that creates a game grid of unlimited size for use with the game of Life. That implementation used a single Python list to store the individual live cells, which was similar to the technique we used with the Sparse Matrix ADT. Explain why the array of linked lists structure used to implement the Sparse Matrix ADT in this chapter cannot be used to implement the Sparse Life Grid ADT.
