我把我的代码提交在这里吧....

[WenYi-China]

Perl实现

say (pack("c*","104","101","108","108","111","32","119","111","114","108","100"));

保存为t.txt
Perl -E t.txt 可以输出对应结果

值得注意的是,say需要perl较高版本作为解释器.

我就是绕不过去 perl5 要么 use 5.10; 要么 perl -E 才能实现，才改成 perl6 的，要不然直接

say v72.101.108.108.111.32.87.111.114.108.100

就好了（
