7楼代码简洁，但感觉效率不如6楼。

terse

这样行不？

@echo off&setlocal enabledelayedexpansion
for /l %%i in (0 1 9) do set %%i=%%i
    for /f "delims=" %%i in (1.txt) do set "str=%%i"&call:lp
    pause&goto :eof
:lp
set/a n+=1
set var=!str:~-%n%,1!
if defined !var! (set str2=!var!!str2!&set lp=lp) else (
    if not defined lp (set str1=!var!!str1!) else (
    set/a str2*=7&set str=!str:~,-%n%!!var!!str2!!str1!
    >>b.txt echo !str!
    for %%i in (str1 str2 n lp) do set %%i=
    goto :eof
    ))
    goto lp

这题就是不让用变量替换才故意给出有重复数字的文本。
我之后生成的文本中有重复数字字串的概率是1%
变量截取可以，但好麻烦。

那到是，还要修代码

楼上代码错了，不可以用替换的
不然所有71的数字都被你替换了

ieutk

是这样理解的吗？
