Budding novice Perl Monk here :D I have this simple code, basically it just guesses a users number in a range, using a binary search. 
use strict;
use warnings;

sub input
{
    print($_[0]);
    return <STDIN>;
}



my $bottom = input("Enter the bottom most number: ");

my $top = input("Enter the top most number: ");

input("Hit enter once you have your number!");

my $middle = int(($bottom + $top) / 2);


my $guesses = 1;

while(1)
{
    my $state = input("Is it " . $middle . "(l/h/t)?: "); 
    chomp($state);
    if($state eq "t")
    {
        input("I Win! It took me " . $guesses . " guesses!");
        last;
    }
    elsif($state eq "l")
    {
        $top = $middle;
        $middle = int(($top + $bottom) / 2);
        $guesses++;
    }
    elsif($state eq "h")
    {
        $bottom = $middle;
        $middle = int((($bottom + $top) / 2) + 0.5);
        $guesses++;
    }
}

So, obviously I need to chomp my $state variable, or it doesn't work. However, I don't need to chomp my number variables($top,$bottom). I'm guessing Perl automagically chomps them when doing mathematical operations? Should I chomp them manually for style? Also, anything also "wrong", or could be done better with my code? Thanks, wise Perl Monks for your time!
