State the language, is it C?

Instructions are a bit inaccurate with regards to what is asked, for example instruction asserts that 'return an empty array', but you actually have to return NULL.

[2, 4, 6, 8, 0, 2, 4, 6, 8, 9, 10, 11, 12, 12] should equal [2, 4, 6, 8, 0, 2, 4, 6, 8, 9, 0, 1, 2, 2] means that your function returned [2, 4, 6, 8, 0, 2, 4, 6, 8, 9, 10, 11, 12, 12], but it should have returned [2, 4, 6, 8, 0, 2, 4, 6, 8, 9, 0, 1, 2, 2] instead. The original input for that test is [1, 2, 3, 4, 5, 6, 7, 8, 9, 9, 9, 9, 9, 8]. Your function works mostly correctly, but there's something in the kata description that you're missing that is causing you to fail.

I think you're misreading something, maybe the error you get is [2,4,3] should equal [2,4,6]? In that case [2,4,3] is what your function wrongly returned, not the input value.

How does [2,4,3] result in [2,4,6]? I must be misunderstanding the question completely. I wouldd have thought it should result in [3,6,6]]

Apologies, I'm an SQL newbie. Shouldn't the name of the table containing the demographics records be provided? I thought I would have to query a table in order to count by unique race. Or perhaps I'm misunderstanding what is required..

Are you sure about that test? If the input is 2, the answer should be also 2 (see the post above)

Because 3 is a prime number, its the nearest prime to 3. The same for 11.

I've struck a problem running my code. Nothing happens! It runs fine in my IDE. Any suggestions would be great.

Also,some of the test examples are listed below. The 2 here have answers that I find puzzling. Are they correct?

Test.it("Basic tests")
Test.assert_equals(solve(3),3)
Test.assert_equals(solve(11),11)

1 is not a prime number.

The instructions say that if 2 numbers are equidistant from the start and are both primes, then the result should be the lower of the 2.
But then in the tests it gives solve(2) = 3. Shouldn't it be solve(2) = 1?
