I have tried for hours to solve this. Ok, the user enters a number, say 2020. 2020 is put into an array. {2, 0, 2, 0}. At @array[0] = 2; 0 occurs twice in the string so this should print true; @array1 1 occurs 0 times in the string so this should return true too. and @array[2] 2 occurs 2 times in the string and this returns true; But when I enter 2020 , I get false true false true. I've looked at this for hours. 
 
#!/usr/bin/perl -w

print "Enter number : ";
my $num = <STDIN>;
chomp($num);

@nums = split /(?<=[\d])/, $num;

$i = 0;
foreach (@nums)
{
    if ($num =~ /[$i]{$_}/)
    { print "true"
    } else {
    print "false"; 
    }
$i++;
}
