Hello guys, I am trying to answer a code-chef problem, using perl. To be specific I am trying to answer this problem. http://www.codechef.com/SEP12/problems/HORSES I am running to an issue however, around lines 6-10, my program seems to freeze after I enter the following (just an example) 
1
2
3 4

It's strange, after the last input taken in, the program just freezes, CPU usage for the process jumps up to 14% and it just sits there, I've tried putting in print statements to check my progress, but it doesn't help. Any ideas? 
#!/usr/bin/perl

$i1 = <>;
chomp($i1);
for ($count = 0; $count < $i1; $count++) {
     $i2 = <>;
    $i3 = <>;
    chomp $i2;
        chomp $i3;
    my @values;
    @values = split(/ /, $i3);

    my @differences;
    my $count1;
    my $count2;
    my $min;

    for ($count1 = 0; $count1 < $i2; $count++) {
        for ($count2 = $count1+1; $count2<$i2; $count2++) {
            if($count1 = 0 and $count2 = 1)
            {
                $min =abs($values[$count1]-$values[$count2]);
            }
            elsif($min> abs($values[$count1]-$values[$count2]))
            {
                $min = abs($values[$count1]-$values[$count2]);
            }
        }
    }
    print $min;
}
