Making many arrays

[FCC]

Hi all,

I want to basically make a multidimensional array. My problem is I don't want to have to explicitly declare 20 arrays and then my other other reference all 20 of them. But rather have 2 foreach loops:

foreach my $i (0 .. 6){
  foreach my $j ( 0 .. 30){
    $snps[$i] = \new @array()
  }
}

Where new @array() just makes an array without any explicit name. Obviously the above code doesn't work. I hope I make sense...is there anyway to do this?

Is this perl?

Makes an array of references to 20 empty arrays

my @array = ();
for (1 .. 20) {#<-number of arrays
   push @array,[];
}

You don't have to set the number of buckets that each array will have when you create them unless there is a real need to do that. Its also pretty rare that you would need to create the array references first. Perl will just make them as necessary during the runtime of your program.
