Hi! I need help about this task:
Before entering the minefield, you are given a matrix 'b' filled with integers where every b[i,j] of them stands for a number of mines around (not includig) the a[i,j] part of the minefield.
The matrix' are NxN where N is a given integer N>=5.
The task is to write matrix 'a' that represents the minefield (if there is a mine then '*' else 's') so you could cross the minefield safely.

example
Input:
5
2 3 4 3 1
3 4 5 4 3
1 3 5 4 3
1 1 2 2 3
0 0 1 1 1

Output:
s * * s s
s * * * s
* s s * *
s s s * s

I've been trying to solve it for days but I can't!
Please help!
Please use only pascal.
Thanks!!!
