思路一般，事先考虑好各组存在的位置。也适用于24小时制时钟。

@echo off&setlocal enabledelayedexpansion
:begin
set /p "_time=请输入时钟制:"
if not "!_time!" equ "12" (
   if not  "!_time!" equ "24"  goto begin
)
set /a a=_time/4,b=a*3
for /l %%i in (1 1 %_time%) do (
    if %%i leq %a% ( 
        set "group1=!group1! %%i"
    ) else if %%i leq %b% ( 
           set "group2=!group2! %%i"
    ) else set "group1=!group1! %%i"
)
echo group1:%group1%
echo group2:%group2%
pause
