oh .. thanks for help I finally got it. :)
I count not_touched like missed shots and not like not touched boats.

int[,] attacks = { { 2, 1 }, { 2, 2 }, { 3, 2 }, { 3, 3 } };
so when I get this attacks result is
3 0 1
3 0 0
0 0 0
0 0 0
but there is no miss. Every attack hit the boat or am I wrong ?

x 1 2 3
y
4 3 0 1
3 3 0 1
2 0 2 1
1 0 2 0

attack= { {x, y } };
so .. numbers in attacks are represented in this grid, aren't they ?

Hi I have bit trouble with understanding.
301

Im not sure if its correct but if I transfer it to The Board output should is same than mine. Where is the problem ? How actualy this attacks works? Which position they attack on?
Thanks for response :)
