Hello, I made a program that generates a random number between 1 and 100 then it tries to guess it using binary search... It works perfectly, the only thing is that it's kinda slow, may be it's the search methode I used... I don't know, anyways, here's the code, please tell me if it can be improved :) 
#!/usr/bin/perl -w
use strict;
my $max = 100;
my $min = 1;
my @numbers = $min..$max;
my $target = int(1 + rand 100);
my $interval;
my $guess;
my $result = 3;

while ($result!=1) {
  $interval = $max - $min;
  $guess = $min + int($interval/2);
  print "\$result = $result; \$min = $min; \$max = $max; \$interval = 
+$interval; \$guess = $guess\n";
  $result = ✓
  ($result == 0) && ($min = $guess);
  ($result == 2) && ($max = $guess);
}
sub check {
  print "\$guess = $guess; \$target = $target\n\n";
  ($guess < $target) ? 0 : ($guess > $target) ? 2 : 1;
}
