Write a program to implement the simulation of life as described in Scientific A

Question

Write a program to implement the simulation of life as described in Scientific American by Martin Gardner. The program will be implemented on a two dimensional surface of size 60 by 60 visible elements. The rules of the simulation are as follows: 1) Aninitialsetofcellsaremarkedas“alive”bytheuser.Thisisgeneration0.Your program will ask the user to input a set of row and column values to let the user determine which cells are “alive”. Display this generation. 2) Cells change for each succeeding generation by the following rules: A living cell dies of overcrowding in the next generation if it currently has 4 or more living neighbors. A living cell dies of loneliness in the next generation if it currently has only 0 or 1 living neighbors. An empty cell becomes a “birth” cell (becomes alive) in the next generation if it has exactly 3 living neighbors. All other cells remain unchanged. 3) The new generation becomes the current generation and is displayed. 4) Afterdisplayingeachnewgeneration,asktheuseriftheywishtocontinuetothe next generation or stop at this point.
