Wow. . .
ps: Brother's code is not universal. What if both sides are letters or Chinese characters?

Please give more advice!~

Tips: intercept characters from both sides at the same time with the middle as the boundary

Both sides are letters?
This can only be blamed on your carelessness in setting the question.

It really is that I thought too, too complicated... I wanted to give up halfway through this problem, FAITH... Now if I do it again, I'm afraid I'll really give up. Such a problem makes my spine hurt when I think about it~

I just explained that the code should improve generality, and there's no other meaning. For this question, he has already solved it, and I don't deny that.

Victory often follows right after the moment when you feel you can't hold on any longer.
ps: Brothers, I'm going to sleep first. I have to go to work tomorrow. Looking forward to someone writing efficient and general-purpose code (mine won't be posted first)...

I think it's not that long. Sign in

But the code for solving the problem must not be short. I think it should not be solvable within 10 lines.

@echo off&setlocal enabledelayedexpansion

set str=0123456789abcdefghij

:lp

set a=%str:~,1%&set /a n+=1

set .%n%=%a%&set _%n%=!str:~-1,1!&set str=%str:~1,-1%

if defined str goto lp

set /p code=please enter the code:

:loop

set a=%code:~,1%&set var=%var% !a!&set code=%code:~1%

if defined code goto loop

for /l %%a in (1,1,%n%) do (

    for %%i in (%var%) do (

        if "!.%%a!" equ "%%i" set flag=a

        if "!_%%a!" equ "%%i" set flag=a

    )

    if defined flag (

       set str1=!str1!!.%%a!&set str2=!_%%a!!str2!&set "flag="

       ) else (

       set str1=!str1!#&set str2=#!str2!

))

cls&echo %str1% ^| %str2%&pause>nul

It seems that this problem is indeed a bit difficult. I'll first公布 my thought - out relatively complex method:

@echo off&setlocal enabledelayedexpansion

set str=0123456789abcdefghij

:lp

set a=%str:~,1%&set /a n+=1

set .%n%=%a%&set _%n%=!str:~-1,1!&set str=%str:~1,-1%

if defined str goto lp

set /p code=please enter the code:

:loop

set a=%code:~,1%&set var=%var% !a!&set code=%code:~1%

if defined code goto loop

for /l %%a in (1,1,%n%) do (

    for %%i in (%var%) do (

        if "!.%%a!" equ "%%i" set flag=a

        if "!_%%a!" equ "%%i" set flag=a

    )

    if defined flag (

       set str1=!str1!!.%%a!&set str2=!_%%a!!str2!&set "flag="

       ) else (

       set str1=!str1!#&set str2=#!str2!

))

echo.&echo  !var1!  !var3!

It's really confusing. It took me quite a while...
There are three methods thought out in total. The first one is not universal, and the latter two are relatively universal.
Generally speaking, I feel that the idea is not as clear as zw19750516's... I'm confused. Got bamboozled...
Code One:
The left side must be a number. (Not universal, only for the topic in the first post)

@echo off&setlocal enabledelayedexpansion

echo.&set /p num= Please enter &cls

set "str=a b c d e f g h i j"

set "var1=##########"

set /a n=10

for %%a in (%str%) do (

  set /a n-=1&set .%%a=!n!&set .!n!=!n!&set "_!n!=%%a"

)

for /l %%a in (0 1 9) do (

  if not "!num:~%%a,1!"=="" set num2=!num2! !num:~%%a,1!

)

for %%a in (!num2!) do (

  set /a n=!.%%a!+1

  call set "var1=%%var1:~0,!.%%a!%%!.%%a!%%var1:~!n!%%"

)

for /l %%a in (0 1 9) do (

  if "!var1:~%%a,1!"=="#" (set var2=#!var2!) else set "var2=!_%%a!!var2!"

)

echo.&echo  !var1!   !var2!

pause>nul

Code Two:
More universal, not limited to numbers, both left and right sides can be any characters but no duplicates.

@echo off&setlocal enabledelayedexpansion

set "str1=abcdefghij"&set "str2=tsrqponmlk"

for /l %%a in (0 1 9) do (

   set ".!str1:~%%a,1!=!str1:~%%a,1!"

   set ".!str2:~%%a,1!=!str1:~%%a,1!"

   set "_!str1:~%%a,1!=#"

   set "_!str2:~%%a,1!=#"

)

echo  !str1!  klmnopqrst

echo.&set /p num= Please enter &cls&echo  !num!

echo.&echo  !str1!  klmnopqrst

set num=!num: =!

for /l %%a in (0 1 9)do if not "!num:~%%a,1!"=="" set num2=!num2! !num:~%%a,1!

for %%a in (!num2!) do set _%%a=!.%%a!&set "_!.%%a!=!.%%a!"

for /l %%a in (0 1 9) do call set "var1=!var1! %%_!str1:~%%a,1!%%"

set /a nnn=-1

for %%a in (!var1!) do (

  set /a nnn+=1

  if "%%a"=="#" (set var2=#!var2!) else call set "var2=%%str2:~!nnn!,1%%!var2!"

)

echo.&echo  !var1: =!  !var2!

pause>nul

Code Three:

@echo off&setlocal enabledelayedexpansion

set "str1=abcdefghij"&set "str2=tsrqponmlk"

set var1=##########&set var2=!var1!

echo  !str1!  klmnopqrst

echo.&set /p num= Please enter &cls&echo  You entered is !num!

echo.&echo  !str1!  klmnopqrst

set num=!num: =!

for /l %%a in (0 1 9)do if not "!num:~%%a,1!"=="" set num2=!num2! !num:~%%a,1!

for /l %%a in (0 1 9) do (

   set /a mmm=%%a+1

   set ".!str1:~%%a,1!=!mmm!"

   set ".!str2:~%%a,1!=!mmm!"

)

for %%a in (!num2!) do (

  set /a hhh=!.%%a!-1

  call set var1=%%var1:~0,!hhh!%%%%str1:~!hhh!,1%%%%var1:~!.%%a!%%

  call set var2=%%var2:~0,!hhh!%%%%str2:~!hhh!,1%%%%var2:~!.%%a!%%

)  

for /l %%a in (0 1 9) do set var3=!var2:~%%a,1!!var3!

echo.&echo  !var1!  !var3!

pause>nul

To be honest, I'm confused by your code... The expert actually came up with three methods.
The idea highlights that this lies in the clever use of variable assignment.
The flaw I think is still in the complexity of the code.

@echo off&setlocal enabledelayedexpansion

set str=0j 1i 2h 3g 4f 5e 6d 7c 8b 9a

set /p code=请输入字符，中间请用空格格开:

for %%a in (%str%) do (set a=%%a

    for %%i in (%code%) do (

        if "%%i" equ "!a:~,1!" set flag=a

        if "%%i" equ "!a:~1!" set flag=a

    )

    if defined flag (

       set str1=!str1!!a:~,1!&set str2=!a:~1!!str2!&set "flag="

       ) else (

       set str1=!str1!#&set str2=#!str2!

))

cls&echo %str1% ^| %str2%&pause>nul

Here is another code I used a bit cleverly (when inputting, it must be in the form like 1 a f 4):

@echo off&setlocal enabledelayedexpansion

set str=0j 1i 2h 3g 4f 5e 6d 7c 8b 9a

set /p code=Please enter characters, separated by spaces in between:

for %%a in (%str%) do (set a=%%a

    for %%i in (%code%) do (

        if "%%i" equ "!a:~,1!" set flag=a

        if "%%i" equ "!a:~1!" set flag=a

    )

    if defined flag (

       set str1=!str1!!a:~,1!&set str2=!a:~1!!str2!&set "flag="

       ) else (

       set str1=!str1!#&set str2=#!str2!

))

cls&echo %str1% ^| %str2%&pause>nul

After seeing the codes of seniors, I feel extremely ashamed...

@echo off&setlocal enabledelayedexpansion

set "str1= 0 1 2 3 4 5 6 7 8 9"

set "str2= j i h g f e d c b a"

echo.&set /p num= 请输入 &cls&set num=!num: =!

for %%a in (!str1! !str2!) do set num=!num:%%a= %%a!

for %%a in (%str1%) do set /a wei+=1,weis=wei*2



for /l %%a in (1 2 !weis!) do (

   set ".!str1:~%%a,1!=!str2:~%%a,1!"

   set ".!str2:~%%a,1!=!str1:~%%a,1!"

)

for %%a in (!num!)do set _%%a=a&set _!.%%a!=a

for %%a in (!str1!)do if defined _%%a (set var1=!var1!%%a) else set "var1=!var1!#"

for %%a in (!str2!)do if defined _%%a (set var2=%%a!var2!) else set "var2=#!var2!"

echo.&echo  !var1!  !var2!

pause>nul

Another one, with a clear train of thought.

@echo off&setlocal enabledelayedexpansion

set "str1= 0 1 2 3 4 5 6 7 8 9"

set "str2= j i h g f e d c b a"

echo.&set /p num= Please enter &cls&set num=!num: =!

for %%a in (!str1! !str2!) do set num=!num:%%a= %%a!

for %%a in (%str1%) do set /a wei+=1,weis=wei*2



for /l %%a in (1 2 !weis!) do (

   set ".!str1:~%%a,1!=!str2:~%%a,1!"

   set ".!str2:~%%a,1!=!str1:~%%a,1!"

)

for %%a in (!num!)do set _%%a=a&set _!.%%a!=a

for %%a in (!str1!)do if defined _%%a (set var1=!var1!%%a) else set "var1=!var1!#"

for %%a in (!str2!)do if defined _%%a (set var2=%%a!var2!) else set "var2=#!var2!"

echo.&echo  !var1!  !var2!

pause>nul
