Hi,

I have been suggested early on my script. Now the script work in the manner i wanted it. I want a slight modification to that.

se warnings;
use strict;

my $str1 = q/It is a guide to action which ensures that the military a
+lways obey the commands of the party./;
my $str2 = q/It is a guide to action that ensures that the military wi
+ll forever heed Party commands is a guide./;

my $n = 0;
while ( $str1 =~ /(?=(\S+\s+\S+\s+\S+))/g ) {
    my $t1 = $1;
    while ( $str2 =~ /($t1)/g ) {
        print "$1\n";
        $n++;
        }
    }

print "No of matching is : $n\n";

No of matching is : 7

In addition to this i want to count the maximum no.of occurence for each matched combination(three elements).

i.e for eg. if "is a guide" appears two times in $str2. its maximum reference count is 2. likewise i want to compute for all the combinations.

my $count=($str2=~ tr/$t1//);

this counts the no. of times $t1 appeared. But i don't know where to put this inside the loop, so that it can be calculated for all the dynamic values of $t1.

Need help in this.. Thanks..
