Hi there,

I have program which compares elements of an array with the sentence and prints if it finds the matching.

I m not only comparing single element rather 3 elements at a time. 

$str1='It is a guide to action which ensures that the military always 
+obey the commands of the party.'; chomp($str1);
$str2='It is a guide to action that ensures that the military will for
+ever heed Party commands is a guide.'; chomp($str2);

@arr1=split(/\s+/, $str1);
 $n=0;
for($i=0; $i<$#arr1;$i++) {
        $t1="$arr1[$i] $arr1[$i+1] $arr1[$i+2]";
        if($str2=~/$t1/) {
                print "$t1\12";
$n++;
        }
}
print "\n No of matching is : $n";

The output is:

It is a
is a guide
a guide to
guide to action
ensures that the
that the military
 
No of matching is : 6.

What i wanted is, when the three elements from $str1 i.e "is a guide" compared with $str2, it should find two matches, but now it outputs only 1 match. Also i want to count no.of matches for each combination. I.e in this case the countOF(is a guide) is equal to 2. Any suggestion..

In reply to count the maximum no.of occurence by sarvan
