Answer 1

@echo off
setlocal enabledelayedexpansion
set s=`abcdefghijklmnopqrstuvwxyz
set /p a=请输入数字，用空格隔开:
for %%i in (%a%) do set /p=!s:~%%i,1!<nul
echo.
set m=0&set /p a=请输入字母，不加空格:
:x0
set n=0&if "!a:~%m%,1!"=="" goto x
:y0
if "!s:~%n%,1!"=="" goto y
if "!s:~%n%,1!"=="!a:~%m%,1!" set /p=%n% <nul&goto y
set /a n+=1&goto y0
:y
set /a m+=1&goto x0
:x
echo.&pause

Answer 2

@echo off&setlocal enabledelayedexpansion
set "str= abcdefghijklmnopqrstuvwxyz"
for /l %%i in (1 1 26) do set !str:~%%i,1!=%%i
set /p Num=请输入数字，用空格隔开:
for %%i in (%Num%) do set /p=!str:~%%i,1!<nul
echo.
set Num=
set /p Num=请输入字母，用空格隔开:
for %%i in (%Num%) do set /p=!%%i!<nul
echo.&pause

Answer 3

@echo off
set /p a="请输入数字或字母："
if %a%==1 echo a
if %a%==2 echo b
if %a%==3 echo c
if %a%==4 echo d
if %a%==a echo 1
if %a%==b echo 2
if %a%==c echo 3
if %a%==d echo 4
pause>nul

对应的作用是输入1，输出a，输入2，输出b……输入a，输出1，输入b，输出2……
