Start with this sample project and expand so that it accepts input in the form of coordinates: "x y". For every coordinate input the program shall follow the rules of the minesweeper game and print the new state of the game.
Initially all coordinates are unvisited, i.e. covered. This shall be illustrated with a "?". The first program output will be:
01234
4|?????
3|?????
2|?????
1|?????
0|?????
If the user then inputs "4 0" the new state will be:
01234
4|?????
3|?????
2|?????
1|??111
0|??1
The program shall uncover all coordinates adjacent to the visited one until a bomb is uncovered
When the state is printed the number of bombs that can be reached from uncovered coordinates shall be output for those coordinates or empty for coordinated with no adjacent bombs.
The program shall ask for coordinates until a bomb is encountered or all bombs have been uncovered.
Feel free to make your own assumptions and change the code as you like.
Test cases that you feel are relevant can be added to the test project. MinesweeperTest uses MSTest but feel free to use another test framework (e.g. nunit, xunit.net etc) or with no framework
Good luck!
