/*
  Chess board
Write a program that creates a string that represents an 8×8 grid, using
newline characters to separate lines. At each position of the grid there
is either a space or a “#” character. The characters should form a chess
board.
Passing this string to console.log should show something like this:
 # # # #
# # # #
 # # # #
# # # #
 # # # #
# # # #
 # # # #
# # # #
When you have a program that generates this pattern, define a variable
size = 8 and change the program so that it works for any size, outputting
a grid of the given width and height.
