    class NumberAverage
    {
        public static string FindAverage(int[] massive)
        {
            int SumOfNumbersInArray = 0;
            if(massive.Length == 0)
            {
                return "Error. Massive length must have at least 1 number";
            }

            foreach(int i in massive)
            {
                if (i < 0)
                {
                    return "Error. Massive must have only positive numbers";
                }
                SumOfNumbersInArray += i;
            }

            return $"{SumOfNumbersInArray / massive.Length}";
        }
    }
