Please note: yours is the kind of question you need to be able to answer by your own efforts if you are trying to learn Perl.

So, just possibly, you might start educating yourself by reading an (almost any) introduction to hashes with an emphasis on keys and values (and, for extra points, scope out the advice here in the Monastery on use strict; use warnings;). (Synopsis: Do so, without fail, unless you know precisely why not. Blatant self-promotion: Re: **HomeWork** Printing the found input from an array)

For starters (and preliminary info; not a direct answer) try perldoc -f keys and perldoc -f values; then proceed directly to planetscape's excellent Not Exactly a Hash Tutorial.

Alternately (or additionally) buy or borrow a copy of "Learning Perl" (Schwartz & Phoenix, O'Reilly); or, since this smells a bit like homework, if it is homework, try the textbook for your course.
