What's the meaning of "Land fragments that are adjacent to the map's
border are not considered as islands." ???

I can hardly understand it ! in the Example input, There is two
island adjacent to the map's border(the north-east corner and the
south-west corner) . but the answer is 3 !!! can anyone help me ?

In the first sample I checked the sacred islands' territory as '*':

........#
.*******.
.*.....*.
.*.*.*.*.
.*.....*.
.*******.
#........

So, there are 3 sacred islands. The land fragments in the corners of
the map are not the islands, because they are adjacent to the map's
border.

but those islands are not in the same sea
