3、取出数组中最大值和最小值

namespace _0

        public static int[] ReturnMaxAndMin(int[] arr)
        {
            int[] result = { arr[0], arr[0] };
            for (int i = 0; i < arr.Length; i++)
            {
                if (arr[i] > result[0])
                {
                    result[0] = arr[i];
                }
                else if (arr[i] < result[1])
                {
                    result[1] = arr[i];
                }
            }
            return result;
        }
        static void Main(string[] args)
        {
            int[] arrary = { 1, 2, 4, 6, 7, 8, -1, 2, -4 };
            int[] numbers = ReturnMaxAndMin(arrary);
            Console.WriteLine("Max number: {0}, Min number: {1}", numbers[0], numbers[1]);
