Hi all,

I have an issue with strings.  I want the intesection of two strings but I'm
not sure how to go about it.  I have two cases.

Case 1:
String 1 has the tail end intersecting with the start of string 2..  eg:

String 1: The quick brown fox jumped over the lazy dog.
String 2: fox jumped over the lazy dog.  And in other news bla bla bla

The problem is I don't know how much is intersecting.
What I've done is to take string 1 and say psudo code

until match found
   string2 =~ /^(value of string1)/
   if match found set flag
   else delete first char of string1
loop again

What is a better way to do this?

Case 2:

The start of String1 intersects with the end of string2  eg:

String1:   And here we are with another string.
String2:   bla bla bla.   And here we are

I don't really know about this one yet...  I haven't gotten to it.

Can anyone pls suggest what I might do?

Thanx
Daniel
