Answer 1

Recursion:

    public static string integerToString(int integerPassedIn)
    {
        ICollection res = new List();
        IntToStringRecusion(integerPassedIn, res);
        if (integerPassedIn < 0) res.Add('-');
        return new string(res.Reverse().ToArray()).PadLeft(1,'0');
    }

    static void IntToStringRecusion(int integerPassedIn, ICollection array)
    {
        if (integerPassedIn == 0) return;
        array.Add((char)(48 + Math.Abs(integerPassedIn % 10)));
        IntToStringRecusion(integerPassedIn / 10, array);
    }
