Minesweeper

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):

1
2
3
4
5
6
+-----+
| * * |
|  *  |
|  *  |
|     |
+-----+

into this:

1
2
3
4
5
6
+-----+
|1*3*1|
|13*31|
| 2*2 |
| 111 |
+-----+

The Scala exercises assume an SBT project scheme. The exercise solution source should be placed within the exercise directory/src/main/scala. The exercise unit tests can be found within the exercise directory/src/test/scala.

To run the tests simply run the command sbt test in the exercise directory.
