Roman Numerals: Step 3

Here’s the current source, just enough to pass the first two test cases:

namespace RomanNumerals
{
    struct Convert
    {
        static const std::string ToRoman(int n)
        {
            if (n == 1)
                return "I";
            return "II";
        }
    };
}

Your source may look slightly different, e.g., maybe you checked for if (n > 1) or you had the sense the other way around. All good.

Now let’s refactor. We could either do nothing or we could be just a little prescient and realize that we can get the 3 case to pass if we used a for loop. Let’s not jump the gun and save that for the next test.

Go ahead and move the /* down below the 3 and get these 3 test cases to pass.
