We recently hired a programmer to create a program that searches for new specific keywords on various webpages. He has done a good job creating the program so far, but we have encountered some obstacles. We need to hire a more experienced programmer to come in and fix the bugs. You would be working with our current programmer as a team. Our current programmer is interviewing candidates, if you can give him good ideas, we will hire you.

## Deliverables

Here's what the current programmer wrote that he needs help on. It will give you more detailed info:

We were making a Keyword search engine. It search for new Keywords in the html Page. for example for Keyword test-->in the html String(This is a test for the keyword test and it went well)

the term test was alerted twice. and saved in a database of alerted keywords so that it is not alerted again.

The database used to get a range to letters from the start of test for example (test for the key) saved in the [url removed, login to view] we can check on the next run if it was displayed or not.

The project fell apart when even one letter used to get change for a range suppose(the html page got updated to(This is a test for keyword test 2nd it went well.)

b/c a got change to 2 The keyword is different and not present in the database and is alerted again. then it is also saved in the database. We solved it by adding a 2letters ignore check say it just ignore the keyword if only a change of 2 letters is present. But now we want to improve the engine. It is the current Idea --> get the html from the page check it for the keywords if test is fount alert the user. on next run if the page is changed then check it against the old html that was save on the previous run. get only the new text that was added to the html and start a search on that text.

Any new Idea is welcomed. What you need to do is make 2 functions public String Diff(String old,String new); and public list Diff(String old,String new);

Public String Diff is simple just return the updated text.

public list Diff(old,new) is a bit complicated. It need to return the Strings in segments like 1st match second match so on soon.

You will need to clear any html tags present in the Strings too.

New Ideas will be welcomed.
