Re: How to empty an array ???

[Albannach]

Taking another approach, depending on the requirements of your algorithm you might just confine your @flowers in blocks using my like so:

use strict;
my @flowers;
{
  my @flowers = qw(rose daisy buttercup);
  # arrange your flowers here
}

print @flowers; # prints nothing as these flowers were never assigned

Mind you, from a readability point of view, re-use of variable names is not generally a good idea in my opinion, as it can be quite confusing to others unless your array is always used for the same purpose (e.g. as working space for some subroutine).
