快速排序.txt

s11ss写的批处理。他把很多C语言中经典的例子都用批处理实现了

@echo off

::::::::Get Original Numbers::::::::
echo Please input some numbers separated from "," , like 2007,9,14,88:
set /a s=0
set /p str=
set /a len=0
set /a nx=0
:c
call set word=%%str:~%len%,1%%
set /a len+=1
if "%word%" equ "," (set /a nx+=1 & call :e)
if not "%word%" equ "" (goto :c)
set /a nx+=1
call :e
goto :o
:e
set /a sn=%len%-%s%-1
call set n%nx%=%%str:~%s%,%sn%%%
set /a s=%len%
goto :eof
