This is a holdover from Friday - it was a slow day, and this is how my idle time was spent. The code below is supposed to generate a random number from a range of numbers provided and then pick another random number and stick that in a different variable. For each guess that it makes its supposed to return too high or too low and then make a new range between low and high. It dies this sort of - but it doesnt always seem to stay within the new range for new guesses. This is probably the 5th or 6th revision of the script - Ive tried a few different variations of the code. 
use strict;
my $low = 1;
my $high = 10;
my @range=($low .. $high);
my $rand=int(rand(@range));
my $seed=-1;
my $count=1;
my $lastguess;
while ( $seed != $rand )
{
    undef @range if ( $ count > 1);
    @range=($low .. $high);
    $lastguess = $seed;
    $seed = int(rand(@range));
    if ( $seed < $rand )
    {
        print "You're too low - $seed (last guess = $lastguess)\n";
        $low=$seed+1;
        $count++;
    }
    elsif ( $seed > $rand )
    {
        print "you're too high - $seed (last guess = $lastguess)\n";
        $high=$seed-1;
        $count++;
    }
}

print "you got it in $count tries\n";
print "seed = $seed  rand = $rand ( last guess = $lastguess )\n";
