Add the numbers to a minesweeper board.
Minesweeper is a popular game where the user has to find the mines using numeric hints that indicate how many mines are directly adjacent (horizontally, vertically, diagonally) to a square.
In this exercise you have to create some code that counts the number of
mines adjacent to a square and transforms boards like this (where *
indicates a mine):
+-----+
| * * |
| * |
| * |
| |
+-----+
into this:
+-----+
|1*3*1|
|13*31|
| 2*2 |
| 111 |
+-----+

For running the tests provided, you will need the Minitest gem. Open a terminal window and run the following command to install minitest:
gem install minitest
If you would like color output, you can require 'minitest/pride' in
the test file, or note the alternative instruction, below, for running
the test file.
Run the tests from the exercise directory using the following command:
ruby minesweeper_test.rb
To include color from the command line:
ruby -r minitest/pride minesweeper_test.rb
