"TestFromImage2" expects five attacks with these rooks: 1-3; 1-5; 3-5; 5-3; 5-3
I think there is something wrong with this test. There is a duplicate rook and the description mentions that there are no duplicate rooks. However, the correct answer should be three and not the expected five.

Thank you Chrono79. Now I understood my misinterpretation.

Thanks for the clarification. But why are [-2, 1, 1] and [-1, -1, 2] duplicates of elements in the expected solution?

Maybe I missed something.

For one of the base test we have given:
arr = [ 1, -1, 2, 3, -2, 4, 5, -3, -3, -1, 2, 1, 4, 5, -3 ]
and
n = 3

This is expected:
expected = [ [ -3, -2, 5 ]
, [ -3, -1, 4 ]
, [ -3, 1, 2 ]
, [ -2, -1, 3 ] ]

Why are [-2, 1, 1] and [-1, -1, 2] not expected?

Thank you everyone for your help.
I learned a lot about arrays in C and the ways of allocating memory.
I also learned about the markup within the comments.

In the future I will only use the issue tag if I'm really sure that there is no bug in my code. But that probably won't be the case with C. ;-)

I think there is something wrong with the C random tests.

I always passing all tests, except one. And every time I am getting this error

Test Crashed

Caught unexpected signal: 6

Sometimes I also get this error but with an extra log. For example this one:

input was:
length : 61
{65, -60, -22, -15, 45, 34, -31, -43, -63, 96, -15, 66, -37, -62, 19, -29, -54, 24, -43, 96, -68, 87, 3, 61, -8, -44, 53, -6, -87, 14, 54, 78, 54, -68, -37, -2, 67, 32, 56, -97, 28, -60, 70, 92, -22, -11, -38, 25, -88, 19, 20, -55, 5, -78, -94, 98, -21, 59, -9, -7, -28}

expected:
length : 16
{28, -60, 70, 92, -22, -11, -38, 25, -88, 19, 20, -55, 5, -78, -94, 98}

but got:
length : 16
{91, 25, -64, -30, 40, 86, -66, -28, 1, 31, -35, 121, -98, 79, -95, -40}

After checking manually I think the expected array is wrong.

Your fix is correct. Now my attempt worked. Thank you.

I'm not using round. Which namespace shoud I use?

Thank you. After writing down the question, it hit me. ^^

Question solved by myself.
