I think most of you are using system named of xp or vista or win7.And these system is consist of a famous game what is mine sweeping.You must have played it before.If you not,just look the game rules followed.
There are N*N grids on the map which contains some mines , and if you touch that ,you lose the game.If a position not containing a mine is touched, an integer K (0 < =K <= 8) appears indicating that there are K mines in the eight adjacent positions. If K = 0, the eight adjacent positions will be touched automatically, new numbers will appear and this process is repeated until no new number is 0. Your task is to mark the mines' positions without touching them.
Now, given the distribution of the mines, output the numbers appearing after the player's first touch.
