There is the following corresponding relationship:
0123456789 | abcdefghij
It is required to write an interactive batch processing.

When inputting 7, the output is as follows:
#######7## | ##c#######
When inputting a5, the output is as follows:
#####5###9 | a###e#####
When inputting 12j, the output is as follows:
012####### | #######hij

1 I will give points according to the problem-solving ideas and skills (focusing on ideas).
2 If you don't want to deal with special characters, you can omit the middle | and not output it.
3 Please pay attention to the generality of the code when solving the problem, and try to keep the code concise (consider the problem complicated, and solve the problem simply).
4 When interacting with the human-computer interface for input, you can try to provide convenience for problem-solving as much as possible.
5 There is no need to write the code part for judging the input characters.

Brother pusofalse was the first to solve this problem on the 15th floor, but his code is obviously too complicated and not general, so only 1 point is added.
I also gave a solution on the 25th floor (the code is still a bit complicated).
There are already multiple solutions (10th floor, 25th floor, 26th floor, 28th floor, 29th floor, 35th floor, 37th floor, 38th floor...),
I still tend to the solution given on the 28th floor (the best solution still needs everyone to evaluate), the code is as follows:
@echo off&setlocal enabledelayedexpansion
set str=0j 1i 2h 3g 4f 5e 6d 7c 8b 9a
set /p code=Please enter characters, separate them with spaces in the middle:
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
I think this code has the characteristics of clear ideas, generality, conciseness, efficiency and so on.
Hereby recommend the code of brother terse as follows:
@echo off&setlocal enabledelayedexpansion
set/p p=Please enter:
set str=27j834fi56a901bghcde
set st=!str!&set pt=!p!
:lp
set ..!p:~%n%,1!=ok&set/a n+=1
set .!str:~,1!=!str:~-1,1!
set str=!str:~1,-1!
if defined str goto lp
:lp1
if defined ..%st:~,1% (set var1=!var1!%st:~,1%&set var2=!.%st:~,1%!!var2!)else (
if defined ..!.%st:~,1%! (set var1=!var1!%st:~,1%&set var2=!.%st:~,1%!!var2!)else set var1=!var1!#&set var2=#!var2!)
set st=!st:~1,-1!&set pt=!pt:~1!
if defined st goto lp1
echo !var1! ^| !var2!
pause

Thank you all for your enthusiastic responses to this post, but the only thing that is insufficient is that basically they are all senior members (quya laotu is actually also a veteran member), and there are few traces of new people. I hope that new people all have the spirit of being brave to challenge, and the original intention of me constantly setting questions is also for this.
