Minesweeper
Have you ever played Minesweeper? It’s a cute little game which comes within a certain Operating
System which name we can’t really remember. Well, the goal of the game is to find where are all the
mines within a M × N field. To help you, the game shows a number in a square which tells you how
many mines there are adjacent to that square. For instance, supose the following 4 × 4 field with 2
mines (which are represented by an ‘*’ character):
*...
....
.*..
....
If we would represent the same field placing the hint numbers described above, we would end up
with:
*100
2210
1*10
1110
As you may have already noticed, each square may have at most 8 adjacent squares.
Input
The input will consist of an arbitrary number of fields. The first line of each field contains two integers
n and m (0 < n, m ≤100) which stands for the number of lines and columns of the field respectively.
The next n lines contains exactly m characters and represent the field.
Each safe square is represented by an ‘.’ character (without the quotes) and each mine square
is represented by an ‘*’ character (also without the quotes). The first field line where n = m = 0
represents the end of input and should not be processed.
Output
For each field, you must print the following message in a line alone:
Field #x:
Where x stands for the number of the field (starting from 1). The next n lines should contain the
field with the ‘.’ characters replaced by the number of adjacent mines to that square. There must be
an empty line between field outputs.
Sample Input
