The default test case has this line:

Assert.AreEqual("Team 1 wins!", Kata.tug_o_war(new int[2,5] { {1,2,3,4,6}, {5,4,3,2,1} } ));

which is invalid. the line needs to be

Assert.AreEqual("Team 1 wins!", Kata.tug_o_war(new int[2,5] { new int[]{1,2,3,4,6}, new int[]{5,4,3,2,1} } ));

Marked as major because the tests fail to run due to this even if the users code is valid.

The instructions could use a bit of work on specifying the anchor.

Thanks I got it, at the end I just had some silly mistakes.

Think the bug lies in your .equals method.

What should you compare ?

I forgot to move those statements, but I still get an error

• It seems your .equals method returns true when 2 vectors .components are of different lengthes.

  Are you sure this is the expected behavior ? ( Isn't (1, 2) equals (1, 2) ? )

• In your .add, .subtract & .dot methods you test first if the vectors are equals.

  That means you can't add (or sub, or dot) (1, 2) & (3, 4)...

Hope it helps.

I postef the code

I know that I could still be wrong but I just dont see it.

Can you post your solution so I can see about it?

I have the correct function/output but the tester function marks it as incorrect
