Prime Factors: Step 11

We’re writing just enough code to make all test cases up to 8 to pass.

Changing the first if to a while does it.

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

That was simple. Nothing obvious to refactor.

The next number, 9 fails with Assert failed. Expected:<3 3 > Actual:<9 >.
