Hi, monks.

Still a beginner at this stuff, so I need to borrow your wisdom. I to find the nth number of the fibonacci sequence using a subroutine. Problem is, I can already get it fine without a subroutine, and I can't figure out a way to get it with a subroutine without messing up my code. By the way, I don't know if I did this right.

use warnings; 
use strict;

my $x = 0;
my $y = 1;
my $third = 0;
my $count;

print "Enter the number you would like to see in the sequence: ";
my $number = <STDIN>;



for ($count = 1; $count<=$number; $count++) {
   $third = $x + $y;
   $x = $y;
   $y = $third;
}

print $y;

Excuse my incorrect spacing. Thanks for the help! -- Update: Solved it (: Thanks for the suggestion, dasgar!
