Hi,
when using
for $i (@phrase), the variable $i becomes an alias for all the elements in the list @phrase. In the first run it contains "apple", then "apple" , then "banana" , etc..
If you have this construct, you don't need the additional counter $j. A bit shorter would be:
for my $elem (@phrase) {
$wordfreq{$elem}++;
}
# or even shorter, but perhaps a bit unreadable:
$wordfreq{$_} for (@phrase);
Update: Thanks to chargrill for pointing out my typo, indeed it should be:
$wordfreq{$_}++ for (@phrase);
When printing out the results you might want to print out the name of what you found, for example:
foreach my $key (sort keys %wordfreq) {
print "$key: $wordfreq{$key}\n";
}
Hope this was the answer you were looking for.
Cheers
Roland
