This appears to be duplicating an error in the original Problem: according to the problem specification, having an input of [1] should yield a result of "false", as there is no OTHER element to compare the 1 to! You can easily fix this inconsistency by either --- changing your problem specification (mention that you can compare to all vector elements, not just the 'other' elements) or --- by changing the correct result to "false" in your Test Suite.
