in reply to hash keys from another file

You do not need to load any file to an array. Just build a hash from the param file, then process the sent file line by line and output the count if you can find it:

#!/usr/bin/perl
use warnings;
use strict;

my %counts;
open my $PARAM, '<', 'param' or die "param: $!";
while (<$PARAM>) {
    my ($count, $word) = split;
    $counts{$word} = $count;
}

open my $SENT, '<', 'sent' or die "sent: $!";
while (<$SENT>) {
    chomp;
    print;
    print " $counts{$_}" if exists $counts{$_};
    print "\n";
}
