Meaning I would compare words and their index in an array of words created from
the two strings. The first mismatch is easily found, but the tricky part is
finding the last one. Here a context driven comparison may help. Instead of
comparing word N in both strings, you compare words N and N-1, taking into
consideration the number of extra words found in previous iterations. I have
not tested this specific case, but can tell you context driven may help. All
depends on whether you need the actual difference returned. If not, life is
easy :-)
