标题: [原创] 常见几种排序的批处理写法 [打印本页]
作者: tyc 时间: 2009-4-17 10:01 标题: 常见几种排序的批处理写法
一、选择排序法- @echo off
- setlocal enabledelayedexpansion
- ::选择排序法
- echo 共输入10个数
- for /l %%i in (1,1,10) do (
- set /p a_%%i=请输入%%i个数
- set str=!str! !a_%%i!
- )
- echo %str%
- for /l %%i in (1,1,10) do (
- set /a b=%%i+1
- for /l %%j in (!b!,1,10) do (
- if !a_%%i! gtr !a_%%j! (
- set /a t=a_%%i
- set /a a_%%i=a_%%j
- set /a a_%%j=t
- )
- )
- )
- for /l %%i in (1,1,10) do (
- set str1=!str1! !a_%%i!
- )
- echo %str1%
- pause>nul
复制代码
二、冒泡排序法- ::冒泡排序法
- @echo off
- setlocal enabledelayedexpansion
- for /l %%i in (1,1,10) do (
- set /p a_%%i=请输入第%%i个数:
- set num=!num! !a_%%i!
- )
- echo %num%
- for /l %%i in (1,1,10) do (
- set /a b=10-%%i
- for /l %%j in (1,1,!b!) do (
- set /a t=%%j+1
- set /a d=a_!t!
- if !a_%%j! gtr !d! (
- set /a x=!a_%%j!
- set /a a_%%j=d
- set /a a_!t!=!x!
- )
- )
- )
- for /l %%i in (1,1,10) do (
- set str=!str! !a_%%i!
- )
- echo %str%
- pause>nul
复制代码
三、后序插入排序法- @echo off
- setlocal enabledelayedexpansion
- for /l %%i in (1,1,10) do (
- set /p a_%%i=请输入第%%i个数:
- set str=!str! !a_%%i!
- )
- echo 你输入的数列是: !str!
- for /l %%i in (1,1,10) do (
- rem set /a b=a_%%i
- rem echo !b!===
- set /a c=%%i+1
- for /l %%j in (!c!,1,10) do (
- if !a_%%j! lss !a_%%i! (
- set /a t=!a_%%j!
- set /a a_%%j=!a_%%i!
- set /a a_%%i=!t!
- )
- )
- )
- for /l %%i in (1,1,10) do set stri=!stri! !a_%%i!
- echo !stri!
- pause>nul
复制代码
四、后序插入排序优化- @echo off
- setlocal enabledelayedexpansion
- for /l %%i in (1,1,10) do (
- set /p a_%%i=请输入第%%i个数:
- set str=!str! !a_%%i!
- )
- echo 你输入的数列是: !str!
- for /l %%i in (1,1,10) do (
- set /a p=a_%%i
- set /a b=%%i+1
- for /l %%j in (!b!,1,10) do (
- if !a_%%j! lss !p! set /a p=a_%%j&set /a pp=%%j
- )
- set /a t=!a_%%i!
- set /a a_%%i=!p!
- set /a a_!pp!=!t!
- )
- for /l %%i in (1,1,10) do set stri=!stri! !a_%%i!
- echo !stri!
- pause>nul

还要四种传统排序,以后再写

我不屑抄别人的代码。。。。。。。。。。。。。
小学生信息学竞赛必须掌握前三种,后四种是中学生要掌握的
象杨辉三角,约瑟夫问题等是小学生掌握的
n阶魔阵问题是初中生要掌握的
你们版主觉的很历害,其实优秀的初中生,如defansive这样的就会做的
但是中学生的题目我很多是做不出来的

你动不动就封人家贴子,动不动就说抄人家的,所以你该被很多人骂!知道为什么?因为你伤人自尊,打击别人的学习积极性!

作者: Batcher 时间: 2009-4-17 16:07 标题: 回复 5楼 的帖子
2楼说的很明确,正是因为不知道真实情况,才分了两种情况询问的。
请问哪句话打击了你的积极性?你认为论坛管理人员在想表达2楼那句话的时候应该采取何种措施才能不打击你的积极性呢?
关于说我“动不动就封人家贴子”,请问你认为我封哪个帖子违反了本论坛的规定?请向管理员投诉,相信管理员能够秉公执法。如果没有真凭实据,我将投诉你污蔑他人。

那就说明是原创了,非常感谢分享了。
哦对了,我不是版主。至于版主们是否认为会排序算法的人就算“很历害”,我也不敢妄自揣测。就我个人而言,小学生、初中生能够掌握这些排序算法,我感到非常钦佩并自叹佛如。

不知楼主是原创还是转帖。如果是原创,当加分鼓励;如果是转帖,望注明出处。
这句话看不出有伤人自尊,打击别人的学习积极性的地方啊。
tyc 会员看来对batcher成见很深啊,但在论坛发表
你动不动就封人家贴子,动不动就说抄人家的,所以你该被很多人骂!知道为什么?因为你伤人自尊,打击别人的学习积极性!
这样的言论不太合适吧。
关于用批处理数字排序,各大论坛多年前以有很多人讨论过,相关代码早以产生。
而本论坛向来尊重原创,所以作为管理员对该主题进行提醒应该是职责内的事
至于你说的小学生、中学生该掌握的,似乎和批处理没有必然联系吧?
batcher对你的提醒并不是因为你的代码技术含量低,而是因为该类代码以出现太多。
就我个人而言,小学生、初中生能够掌握这些排序算法,我也是非常感到非常钦佩并自叹佛如。

哦!还有这么多种排序!!学习
作者: 小勇12 时间: 2009-4-20 21:56
真牛。
哈哈
基数排序总不能用批处理写了啥
作者: wc726842270 时间: 2011-2-23 15:44
经典,可惜仅用VBS写过冒泡排序,学习了
作者: wslqy 时间: 2011-3-20 13:28
楼主辛苦了,学习学习下先
作者: 2010sftv 时间: 2011-3-20 18:31
进来学习一下算法。
作者: wangqi0077 时间: 2011-5-22 16:44
这些个东西,,能不能详细分开了讲讲原理等东西,,,新手表示,完全不知道是什么.

@echo off
setlocal enabledelayedexpansion
::选择排序法
echo 共输入10个数
for /l %%i in (1,1,10) do (
set /p a_%%i=请输入%%i个数
set str=!str! !a_%%i!
)
echo %str%
for /l %%i in (1,1,10) do (
set /a b=%%i+1
for /l %%j in (!b!,1,10) do (
if !a_%%i! gtr !a_%%j! (
set /a t=a_%%i
set /a a_%%i=a_%%j
set /a a_%%j=t
)
)
)
for /l %%i in (1,1,10) do (
set str1=!str1! !a_%%i!
)
echo %str1%
pause>nul
请问这行“set str=!str! !a_%%i!”命令中的“!str! !a_%%i!”
是什么意思啊 ?为什么有2个变量没用其他运算符,而是空格
