//showRemainingMines( int i),checkIsRight(),FindBlankButton(int i,int j) and so on .When player click the left key of 
//the mouse,if you find the number of the mines around the square,click the right key ,square will be marked as mines.
//When player mark all the mines ,he/she will find the result .
