This is a somewhat common little exercise: Write a function

When printed, here is the output for size 11:

What interesting, boring, efficient, slow, etc. ways are there?
Ali
Probably, the most boring way is
foreach(i; 0..N)
{
foreach(j; 0..N)
write(" *"[i + j >= N/2 && i + j < 3*N/2 && i - j <=
N/2 && j - i <= N/2]);
write(" *"[abs(i-N/2) + abs(j-N/2) <= N/2]);
writeln;
}
