Comparing strings --- inserted sentences

[hotmailisforloosers]

I have two strings side by side that compare to eachother and highlight the differences (one is a modified version of the other).

I am comparing by sentence right now (thanks to a suggestion that I split it up by the periods). My problem is that if there is a sentence inserted or deleted from the string then it throws the whole thing out of wack. It compares each array item in order, so when a new one is added, all the rest are thrown off.

So I've been thinking about how to accomplish this, and I decided to try and read the difference between the arrays, then use that difference to jump forward or back to try and find a sentence that matches. I've been finding it almost impossible to put this into practice though, with the array going out of bounds every time I try and test even the smallest thing.

I'm going to keep plugging at this from that angle, but since I am a pretty new programmer I was wondering if a wise old vet might know a better way of handling this problem.... or could maybe even show me how to put my own logic into practice

Thanks!

Search Google for "Longest Common Subsequence" and "edit distance".

By the way, "looser" is the comparative form of the adjective "loose" i.e. "not firmly fastened or fixed in place". You can not "pluralize" it.

Thanks, I'll check it out.

... I know, it's a bad joke. That's the username to my hotmail account....... a little dorky self-deprecating humor because I couldn't get anything else to take as a username. I'm not uneducated... just a freak

So to paraphrase, you're proud to be an educated freak ;-)

Thanks, I'm thinking this task is pretty advanced for an intern.... I've made some decent progress on it, but it's getting to the point where I can't hold it all together in my brain........ especially with what you just showed me... ouch, it hurts.

So I'll probably end up screaming to my co-workers for help. I think they were expecting a little much from me, or simply didn't realize all that this would entail.
