Your Help Needed
If you know Perl, please write code for some of the tasks not implemented in Perl.
Perl is both the name of a programming language and the name of the primary implementation of that language.
If you know Perl, please write code for some of the tasks not implemented in Perl.
As a language, it takes the best from other programming languages such as BASIC, Lisp, C and the Unix tools sed, AWK and the UNIX shell. It is particularly suited for Unix systems programming, text processing and gluing heterogeneous programs together. Its interpreter is called perl. Perl has seen five major revisions, and a sixth is currently being worked on.
The implementation known as Perl is available on a wide variety of mostly UNIX-based operating systems.
