Hi,
I have two following strings: 

my $s1 = "1,0,CTGCCACCGCTGT";
my $s2 = "1,5,ACCGCTGTGTTTCGGCCGGCGA";

#The format show this: sequence_index,string_pos,$string
#So the two strings above are in the same sequence 1.

How can I intersect the above two strings so that we obtain: 
CTGCCACCGCTGT                (s1)
     ACCGCTGTGTTTCGGCCGGCGA  (s2)
     ********
     ACCGCTGT                (intersected string)
                             
and also to identify the position of the interesected string,
in this case 6
