I have a simple hash, and would like to return the $key based on $value criteria. That is, for line 14, what code would I need to return the $key where the $value is "yellow"?
1 #!/usr/bin/perl
2
3 # This program creates a hash then
4 # prints out what is in the hash

6 %fruit = (
7 'apple' => ['red','green'],
8 'kiwi' => 'green',
9 'banana' => 'yellow',
10 );
11
12 print "The apple is @{$fruit{apple}}.\n";
13 print "The kiwi is $fruit{kiwi}.\n";
14 print "What is yellow? ";
