Question

随便输入一组数字，并实现按从小到大和从大到小的排序，之后，输入一个数字，插入到原数据中，仍然保持以上两种排序次序。同时输出显示。

Answer 1

            List<int> list = new List<int>();            list.Add(1);
            list.Add(24);
            list.Add(11);            list.Sort();
            Console.WriteLine("从小到大：");
            foreach (int i in list)
                Console.WriteLine(i);            list.Reverse();
            Console.WriteLine("从大到小：");
            foreach (int i in list)
                Console.WriteLine(i);            list.Add(10);            list.Sort();
            Console.WriteLine("从小到大：");
            foreach (int i in list)
                Console.WriteLine(i);            list.Reverse();
            Console.WriteLine("从大到小：");
            foreach (int i in list)
                Console.WriteLine(i);

    public class NumberChoose
    {
        public static void Main()
        {
            InputChoose();
        }        public static void InputChoose()
        {
            string stringNumber = Console.ReadLine();
            //如果没有输入多个数字则表示插入
            if (stringNumber.IndexOf(",") < 0)
            {
                InsertNumber(stringNumber);
            }
            else
            {
                InputNumber(stringNumber); 
            }
        }        private static string[] result = null;
        //排序
        public static void InputNumber(string stringNumber)
        {
            //分割数字
            string[] NumberList = stringNumber.Split(new String[] { "," }, StringSplitOptions.RemoveEmptyEntries);
            //排序
            string temp = "";
            for (int i = 0; i < NumberList.Length; i++)
            {
                for (int j = 0; j <= i; j++)
                {
                    if (int.Parse(NumberList[i]) < int.Parse(NumberList[j]))
                    {
                        temp = NumberList[i];
                        NumberList[i] = NumberList[j];
                        NumberList[j] = temp;
                    }
                }
            }
            result = NumberList;
            Output();
        }
        //输出
        public static void Output()
        {
            //显示顺序排序结果
            for (int i = 0; i < result.Length; i++)
            {
                Console.WriteLine(result[i]);
            }
            //显示倒序排序结果
            for (int i = result.Length - 1; i >= 0; i--)
            {
                Console.WriteLine(result[i]);
            }
            InputChoose();
        }
        //插入
        public static void InsertNumber(string numberString)
        {
            string[] newResult = new String[result.Length + 1];
            int j = 0;
            for (int i = 0; i < result.Length; i++)
            {
                if (int.Parse(result[i]) > int.Parse(numberString) && j == 0)
                {
                    newResult[i] = numberString;
                    newResult[i + 1] = result[i];
                }
                else if (j == 1)
                {
                    newResult[i + j] = result[i];
                }
                else
                {
                    newResult[i] = result[i];
                }
            }
            result = newResult;
            Output();
        }
    }以,分割的
1、输入1,4,8,6 这样的数据表示原始数组，如果输入不包含,的则表示插入的
2、如果第二次输入,分割的则重新排序

Answer 4

//插入
        public static void InsertNumber(string numberString)
        {
            string[] newResult = new String[result.Length + 1];
            int j = 0;
            for (int i = 0; i < result.Length; i++)
            {
                if (int.Parse(result[i]) > int.Parse(numberString) && j == 0)
                {
                    j=1;
                    newResult[i] = numberString;
                    newResult[i + 1] = result[i];
                }
                else if (j == 1)
                {
                    newResult[i + j] = result[i];
                }
                else
                {
                    newResult[i] = result[i];
                }
            }
            result = newResult;
            Output();
        }无语的错误

Answer 5

list或者Arraylist 提供了排序函数的  sort,反转函数Reverse

Answer 6

       public static List<int> Power3(decimal value)
        {
            List<int> result = new List<int>();
            for (int j = value.ToString().Length; j>0; j--)
            {
                int itemp = Convert.ToInt32(Decimal.Remainder(value, (Decimal)Math.Pow(10, j)) / (Decimal)Math.Pow(10, (j - 1)));
                result.Add(itemp);
            }
            result.ToList<int>().OrderBy(t => t).ToList<int>().ForEach(t => Console.Write(t));//小到大
            Console.WriteLine();
            result.ToList<int>().OrderByDescending(t => t).ToList<int>().ForEach(t => Console.Write(t));//大到小
            Console.WriteLine();
            result.Add(8888);            result.ToList<int>().OrderBy(t => t).ToList<int>().ForEach(t => Console.Write(t));//小到大
            Console.WriteLine();
            result.ToList<int>().OrderByDescending(t => t).ToList<int>().ForEach(t => Console.Write(t));//大到小
            Console.WriteLine();            Console.ReadKey();            return result;
        }调用
              Console.Write("输入数字：");
              string temp= Console.ReadLine();
              Power3(Convert .ToDecimal (temp));
