Like a lot of monks, I am not one to completley write code for someone. Especially since it sounds like an assignment (since you are specifying the exact number of lines you need it in). However, to open the file up, check out
IO::File, read in the line, put the vars into an array and then sort them:
for my $line (<FH>) {
my @unsorted = split / /, $line;
# sort ascending
my @sorted = sort @unsorted;
# sort descending
my @desc_sort = reverse @sorted;
}
Check out the pages on
sort,
reverse, and
split for more information. There are certainly shorter ways to do this, but you need to understand what's going on before you can condense it.
