编程模拟“地雷游戏”。在9*9的方格中，随机布上n(n<20)个“地雷” （有雷为9，无雷为0）。1）按9行9列输出地雷的分布情况（有雷 ‘*’ 表示，无雷输出‘0’）；2)统计并输出各方格周边雷的数目（在有相邻地雷的格子内进一步标出相邻地雷数）。注意：①地雷的个数n在程序运行中指定。②地雷的个数n必须与指定的个数相同。-Programming Simulation " landmine game."　In Box 9* 9,, n (n < 20) a " mine"　(9 thunder, no lightning 0) random cloth. 1) Press the 9 lines of output distribution of landmines 9 (thunder ' *'　indicates, no thunder output ' 0 ' )　number 2) statistics and the parties to the grid surrounding mine output (within a lattice of adjacent mines further mark the number of adjacent mines). Note: ① n specifies the number of mines in the program run. ② mines specified number n must be the same number.
