只写个找相同项的演示代码

@echo off&setlocal enabledelayedexpansion
for /l %%a in (1,1,50) do (
    set nums=!nums! %%a
    set _%%a=### !random:~-1! ### ### !random:~-1!  ###
)

for /l %%a in (1,1,50) do (
    set nums=!nums: %%a=!
    set yn=%%a列
    for %%b in (!nums!) do (
	if "!_%%a!" equ "!_%%b!" (
	   set nums=!nums: %%b=!
	   set yn=!yn! %%b列
	)
    )
    if "!yn!" neq "%%a列" (
	echo; !yn! 相同，内容为：
	echo;!_%%a!
	echo;
    )
)
