Prime Factors: Step 10

We’re writing just enough code to make all test cases up to 6 to pass.

Changing the first if statement to be more general, by checking for even-ness, not just 4, does it.

static std::vector<int> Of(int n)
{
    std::vector<int> v;
    if (n%2 == 0) {
        v.push_back(2);
        n /= 2;
    }
    if (n != 1)
        v.push_back(n);
    return v;
}

Nothing obvious to refactor. The next number, 7, will just pass. But 8 fails with Assert failed. Expected:<2 2 2 > Actual:<2 4 >.
