chaos_cat,

Thank you very much for taking time to "play" with my problem and also for the patience with my incomplete requirements.

Some clarifications:
- the new words will not modify the position in the string of the words that follow (this is true for the original string as well as for the modified string).

e.g.
----

original: Perlmonks is ..................... the best [perl] ...................[community]
modified: Perlmonks is <one> <of> the best [community] <of> [perl] <users>

Note: "the" is the 3rd word in the original and it is considered to be the 3rd word in the modified string also because "<one>" and "<of>" are new words and should be ignored (will not increase the position value)

while

original: ..... the best [perl] ....................[community]
modified: ... the best [community] <of> [perl] <users>

Note: "perl" and "community" should be marked as changed/moved, because they changed the position in the sentence.

words ranks:
------------
original: ......1.......2....................3....4.....[5].............[6]...........
modified: ....1.......2..<7>..<8>...3....4.....[6]...<9>...[5]......<10>.

Please let me know if you don't understant what I tried to explain above and I will explain it in different words.

Thanks a lot.
