翻转排序字符串

[aimeast]

闲着没事，把字符串按翻转顺序排序。

例如原数组是：

string[] st = new string[] { "sadfwea", "vmeoijbrt", "gr", "btrjheb", "ernbrek", "faer", "n", };

按翻转排序后的结果是

sadfwea
btrjheb
ernbrek
n
faer
gr
vmeoijbrt

在如下框架内

        static void Main()
        {
            string[] st = new string[] { "sadfwea", "vmeoijbrt", "gr", "btrjheb", "ernbrek", "faer", "n", };
            var ss = Fun(st);
            foreach (var item in ss)
            {
                Console.WriteLine(item);
            }
        }

        static string[] Fun(string[] st)
        {
            // ToDo::
        }

引用 3 楼 wanghui0380 的回复:

C# codestaticvoid Main()
{string[] st=newstring[] {"sadfwea","vmeoijbrt","gr","btrjheb","ernbrek","faer","n", };var ss= Fun(st);foreach (var itemin ss)
{
Console.WriteLine(item);
}
}staticstring[] Fun(string[] st)
{// ToDo::return st.OrderBy(c=> c.Substring(c.Length-1,1)).ToArray();
}

3楼这个有错

什么叫反转排序 不懂

[波导终结者]

是按字符串的最后一个字符来排序，而不是传统的第一个字符……这种叫翻转排序很容易导致误解

[wanghui0380]

  static void Main()
        {
            string[] st = new string[] { "sadfwea", "vmeoijbrt", "gr", "btrjheb", "ernbrek", "faer", "n", };
            var ss = Fun(st);
            foreach (var item in ss)
            {
                Console.WriteLine(item);
            }
        }

        static string[] Fun(string[] st)
        {
            // ToDo::
            return st.OrderBy(c => c.Substring(c.Length - 1, 1)).ToArray();
        }

不说的真的不知道是什么意思

[绿色夹克衫]

using System;

namespace CSharpTest
{
class Program
{
static void Main(string[] args)
{
string[] st = new string[] { "sadfwea", "vmeoijbrt", "gr", "btrjheb", "ernbrek", "faer", "n", };
Array.Sort(st, Compare);
}

static int Compare(string a, string b)
{
int length = a.Length > b.Length ? a.Length : b.Length;

for (int i = 1; i <= length; i++)
{
if (a[a.Length - i] > b[b.Length - i])
return 1;
else if (a[a.Length - i] < b[b.Length - i])
return -1;
}

return 0;
}
}
}

[smallmaster]

static string[] Fun(string[] st) {
// ToDo::
var list=st.ToList();
list.Sort(Compare);
return list.ToArray();
}
static int Compare (string strA,string strB){
//for(int i=strA)
int indexA = strA.Length - 1; int indexB = strB.Length - 1;
for (; indexA >= 0 && indexB >= 0; indexA--, indexB--) {
char charA = strA[indexA];
char charB = strB[indexB];
if (charA != charB) {
return charA.CompareTo(charB);
}
}
return 0;
}

[gghlkk]

static string[] Fun(string[] st)
{
   return st.Reverse().OrderBy(str => System.Text.RegularExpressions.Regex.Match(str,@"\w$").Value).ToArray<string>();
}

ls把问题理解错了吧？

字符串按翻转顺序排序?

[绿色夹克衫]

Linq版，效率较低

using System;
using System.Linq;

namespace CSharpTest
{
class Program
{
static void Main(string[] args)
{
string[] st = new string[] { "sadfwea", "vmeoijbrt", "gr", "btrjheb", "ernbrek", "faer", "n", };
var result = from item in st orderby item.Aggregate("", (acc, c) => c + acc) select item;
}
}
}

如果是按 字符串按翻转顺序排序的话

那就是
st.OrderBy(c => new string(c.ToCharArray().Reverse().ToArray())).ToArray();

谢谢8L提醒 确实理解错了 更正下

st.OrderBy(str => new string(str.AsEnumerable<char>().Reverse<char>().ToArray<char>()));
