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

3 0 1   ->   3 0 1
3 0 1   ->   3 0 X
0 2 1   ->   0 X X
0 2 0   ->   0 X 0

expected is:

{ 'sunk': 1, 'damaged': 1 , 'not_touched': 1, 'points': 0.5}"
   ship 2      ship 1          ship 3

which seems pretty much consistent to me. ;)

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 ?

Yes, that's it.

;)

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 ?

Should be good, now.

meaning, something like this as for a 3x6 grid?

[[0 0 0 0 0 0],
 [0 0 0 0 0 0],
 [0 0 0 0 0 0]]

If so, read the description again. If not, please let me know.

EDIT: ok, I've seen it. I'll take care of that and keep you posted.

not correct. ;) Read again the part that explains how to use the attacks coordinates (that's not any usual use of them)

Hi I have bit trouble with understanding.

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 :)
