1、排序一个有大小字符，数字组成的字符串，例如EBa37-->37BEa

            string inputs = "EBa37";            char[] result = inputs.ToCharArray();            char copyInputs;            for (int i = 0; i < result.Length - 1; i++)            {                for (int j = i; j < result.Length; j++)                {                    if (result[i] > result[j])                    {                        copyInputs = result[j];                        result[j] = result[i];                        result[i] = copyInputs;                    }                }            }        }

2、判断一个输入是不是水仙花状，如66566,2b22b2是，123321k不是

            string inputs = "123321k";            int stringLength = inputs.Length;            bool isFlower = true;            for (int i = 0; i < stringLength / 2; i++)            {                if (inputs[i] != inputs[stringLength - i - 1])                {                    isFlower = false;                    break;                }            }

3、转换2进制、8进制、16进制表示的数字转换成为Decimal类型，任意选用语言，不得使用语言内部实现的类型转换函数/方法
如果使用.NET提供的转换则：Console.Write(Convert.ToInt32("101", 8));

        static void ConvertType(string value, int type)        {            double currentType = Convert.ToDouble(type.ToString());            decimal hello = 0;            int powIndex = -1;            for (int i = value.Length - 1; i >= 0; i--)            {                powIndex++;                if (Convert.ToDouble(value[i].ToString()) != 0)                {                    hello += (decimal)System.Math.Pow(currentType, powIndex);                }            }            Console.Write(hello);        }

4、把一个数组中的重复元素挑出来然后并到数组尾部
(1)把重复的放到数组尾部

            string stringInputs = "benqbqcbqs";            char[] userChar = stringInputs.ToCharArray();            List<string> list = new List<string>();            StringBuilder sbRepeateObject = new StringBuilder(userChar.Length);            string userObject = "";            for (int i = 0; i < userChar.Length; i++)            {                userObject = userChar[i].ToString();                if (!list.Contains(userObject))                {                    list.Add(userObject);                }                else                {                    sbRepeateObject.Append(userObject.ToString());                }            }            list.Add(sbRepeateObject.ToString());

(2)把所有重复的字符都放至数组尾部

            string stringInputs = "benqbqcbqs";            string repeatString = "";            string originString = "";            string currentString = "";            for (int i = 0; i < stringInputs.Length; i++)            {                currentString = stringInputs[i].ToString();                if (Regex.Matches(stringInputs, currentString).Count == 1)                {                    originString += currentString;                }                else                {                    repeatString += currentString;                }            }            Console.WriteLine(originString + repeatString);
