Hello Perl_Ally, and welcome to the Monastery!

muba has answered your question; I’ll just add a couple of comments:

  1. The syntax sort { $a <=> $b } does sort numerically, but in ascending order. To get descending order, you reverse $a and $b: sort { $b <=> $a }.

  2. The syntax @array[...] is called an array slice. See perldata#Slices.

Hope that helps,
