Use the following code
Code:
open FH, "<inp" or die "Can't open file : $!\n";
my @data=<FH>;
my @result;
my @count;
foreach (@data )
{
    push(@result,split);
}
for ( my $i=4; $i <= $#result; $i=$i+5 )
{
    push(@count,$result[$i]);
}

my %count_hash;
shift @count; #to remove the e from the array
foreach my $word (@count)
{
       $count_hash{$word}=$count_hash{$word}+1;
}

foreach my $word (keys %count_hash)
{
            print $word," Comes for ",$count_hash{$word}," times\n";
}

The output I am getting is follows

Code:
6 Comes for 1 times
4 Comes for 1 times
3 Comes for 1 times
2 Comes for 2 times
