The game of life, invented by J. Conway, is intended to model life in a society

Question

The game of life, invented by J. Conway, is intended to model life in a society of organisms. Consider a rectangular array of cells, each of which may contain an organism. If the array is viewed as extending indefinitely in both directions, then each cell has eight neighbors, the eight cells surrounding it. In each generation, births and deaths occur according to the following rules:

Write a program to play the game of life and investigate the patterns produced by various initial configurations. Some configurations die off rather rapidly; others repeat after a certain number of generations; other change shape and size and may move across the array; and others may produce gliders that detach themselves from the society and sail off into space!

Max dimensions of the array

Initial layout of the organisms

#of generations to be generated

The shape of the organisms in each generation.

The shape of the organisms at the end.
