Lesson 20. Capstone: A slice of life

For this challenge, you will build a simulation of underpopulation, overpopulation, and reproduction called Conway’s Game of Life (see mng.bz/xOyY). The simulation is played out on a two-dimensional grid of cells. As such, this challenge focuses on slices.

Each cell has eight adjacent cells in the horizontal, vertical, and diagonal directions. In each generation, cells live or die based on the number of living neighbors.

20.1. A new universe

For your first implementation of the Game of Life, limit the universe to a fixed size. Decide on the dimensions of the grid and define some constants:

const ( width ...
