Here is another link. I can't really help you too much as I'm not familiar with this data structure. It seems fairly specialized.
@james sir, You are solution to every problem of mine. Your "little" help is "too too much" for me. Can you please read it (it will hardly take 10 min to you to get the concept) and explain me a litle bit. please ?

I think you overestimate my ability. I find this data structure neither interesting nor important to learn to the point where I'm qualified to teach about it, so I have no intention of spending my free time doing so. Sorry.
:'( in even free time, you are doing this. :'( okies. anyways, you are still a CHAMP for me :(
