出題目的：
掌握任意數列之間的排序技巧
解題要求：
代碼通用、高效
盡量簡潔
盡量不生成臨時文件
加分規則：
1 思路獨特基準分5分
2 代碼高效、通用基準分4分
3 技巧高超基準分3分
4 代碼簡潔基準分2分
5 完美代碼加分15分
題目如下：
給出任意一組數列，正序輸出，如：
3 2008 11 19 777 23 2014 453 789 51
輸出為：3 11 19 23 51 453 777 789 2008 2014
說明：
不必考慮特大數，所給的數列中都是整數值。

代碼如下:
cls&@echo off&setlocal enabledelayedexpansion
set "strings=3 2008 11 19 777 23 2014 453 789 51"
echo %strings%
set/a n=0
for %%i in (%strings%) do (
set/a n+=1
set num[!n!]=%%i
)
call :quicksort num 1 %n%
for /l %%i in (1,1,%n%) do echo !num[%%i]!
pause&goto:eof
:QuickSort
::code by dishuostec
::use call :quicksort arrary low high
set "ARR=%1"
set/a dep=0
call :QS %2 %3
goto:eof
:QS
set/a dep+=1,lTmpLow=%1,lTmpHi=%2,Low=%1,Hi=%2
if %Hi% leq %Low% set/a dep-=1&goto :eof
set/a lTmpMid=(Low+Hi)/2
call set/a vTempVal=%%%ARR%[!lTmpMid!]%%

)

)
set/a lTmpLow[%dep%]=lTmpLow,Hi[%dep%]=Hi
if %Low% lss %lTmpHi% call :QS %Low% %lTmpHi%
call set lTmpLow=%%lTmpLow[!dep!]%%&call set Hi=%%Hi[!dep!]%%
if %lTmpLow% lss %Hi% call :QS %lTmpLow% %Hi%
set/a dep-=1&goto :eof
terse：
代碼如下:
@echo off&setlocal enabledelayedexpansion
set str=3 2008 11 19 777 23 2014 453 789 51
for %%i in (%str%) do (
set str=0000000000%%i
set .!str:~-10! !random!=%%i
)
for /f "tokens=2 delims==" %%i in ('set .') do set/p=%%i <nul
pause>nul
MKL：
代碼如下:
@echo off&setlocal enabledelayedexpansion
set "p=3 2008 11 19 777 23 2014 453 789 51"
for %%i in (%p%) do (
set t=1
for %%r in (%p%) do (
if %%i gtr %%r set /a t=!t!+1
)
set !t!=%%i
)
echo !1! !2! !3! !4! !5! !6! !7! !8! !9! !10!

set /a num=1,n+=1
for %%b in (%hang%) do (
if %%a gtr %%b set /a num+=1
)
call :next !num!
set !num!=%%a
)
for /l %%a in (1,1,%n%) do echo !%%a!
