系统是fedora-core2，自带了vim-6.2.457，因为有如下问题，又装了vim-6.3，还是不行。本以为可以改配置文件，可找不到它的配置文件，没办法，只好请教大家了。 具体问题是： 进入vi，在输入状态下，分别按“上”“下”“右”“左”键，得到的“A＋换行”“B＋换行”“C＋换行”“D＋换行”

A system administrator was asked to log information on possible security breaches on a server.Which file should additional entries be added to capture this information? A:/var/adm/sulog B:/etc/syslog.conf C:/etc/security/sysck.cfg D:/etc/security/login.cfg

use strict; use warnings; my $a; my $b; my $c; my $d; for ($a=0;$a<=9;$a++) { for ($b=0;$b<=9;$b++) { for ($c=0;$c<=9;$c++) { for ($d=0;$d<=9;$d++) { if(("$a != $b != $c != $d") && ("($a*1000+$b*100+$c*10+$d)*$d" == "$d*1000+$c*100+$b*10+$a")) { print "$a $b $c $d\n"; } } } } } 对吗?
