Question

I have a file being read in then changed into an array then counted and put into a hash table. I then read in another file that has stop words into an array. I want to take the array of stop words and compare it to the hash table and if a word from the stop words is a match then it deletes it from the hash table.

I’m curious as to what methods I could do to achieve this using perl. I wont post my code, because I’m refraining from having other people write my code. I just would like to know how I could go about this. If someone has a good website I could reference that could help.

Try this:

my %table = some_sub_to_populate_table();
my @stop_words = some_sub_to_get_stopwords();
for my $stop_word ( @stop_words ) {
    delete $table{ $stop_word };
}
