//看清以上数字排列的规律,设1点的坐标是(0,0),X方向向右为正,y方向向下为正。例如,7的坐标为
//(-1,-1),2的坐标为(0,1),3的坐标为(1,1)。编程实现输入任意一点坐标(x,y),输出所对应得-Show the spiral queue,// spiral queue.

For example, 7 of the coordinates// (-1,-1), 2 coordinates for (0,1), 3 coordinates for the (1,1). Programming enter coordinates of any point (x, y), the output corresponding to a
