The following code may be not simple:
===code===
#!/usr/bin/perl
use warnings;
use strict;
my %hash = ("abc"=>"mallik","xyz"=>"ariun","mno"=>"priya");
my %hash2 = ("abc"=>"123","xyz"=>"243","mno"=>"532");
foreach (keys %hash2) {
$hash{$hash2{$_}} = $hash{$_};
delete $hash{$_};
}
foreach (keys %hash) {
print "$_ ==> $hash{$_}\n";
}
