( #3333=superdoc: print w/ replies, xml ) Need Help??
Hello, I'm just wondering whether it will be possible to create an hash of arrays using a faster method than the second solution provided in the code below:
# WRONG { my %hash; my @cols = qw(min max sum); my @values = qw(1 3 4); @hash{@cols} = @values; use Data::Dumper; print Dumper \%hash; } # CORRECT (but slow) { my %hash; my @cols = qw(min max sum); my @values = qw(1 3 4); foreach my $col (@cols) { push @{$hash{$col}}, shift @values; } use Data::Dumper; print Dumper \%hash; }
Thanks in advance.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
