Problem Statement

There is an n by m grid that has a random number (between 10% to 20% of the total number of tiles, though older implementations may use 20%..60% instead) of randomly placed mines that need to be found. Positions in the grid are modified by entering their coordinates where the first coordinate is horizontal in the grid and the second vertical. The top left of the grid is position 1,1; the bottom right is at n,m. The Task is to create a program that allows you to play minesweeper on a 6 by 4 grid, and that assumes all user input is formatted correctly and so checking inputs for correct form may be omitted. You may also omit all GUI parts of the task and work using text input and output. Note: Changes may be made to the method of clearing mines to more closely follow a particular implementation of the game so long as such differences and the implementation that they more accurately follow are described.
