I've heard of this technique many times but haven't found any suitable tutorial on it. I'll be glad if someone explains it, how it works, where it can be used, sample code of it or some sample problems.

Thanks in advance.

Well, hi there, thanks for noticing this blog. First of all, I beg your pardon for my poor English.

It's natural and usual to get depressed, again and again, in life, of-course in competitive world like competitive programming or should I use the word "code sprinter". I've been (seriously) in this section for less than 6 months. I've never (or I can't remember if I ever) been so much upset as I am today (it's a lie, I've been but very few times). I was reading about someone who was top of the country in ACM-ICPC regional contest when he was in high-school!! Though their team was an unofficial team. It was suppose to be encouraging but I dunno why I am outta mood after reading that article.

I didn't know about informatics olympiad when I was in school or high-school. I came to know about math olympiad at high-school but I didn't know what is it or how to participate in it. I talked about it with my mother and she encouraged me a lot to participate in a competition and I did too. But couldn't solve any of the problems! That's the end of story.

I wasn't bad at math or solving puzzle and I was in a well renowned institute in my country and I always had (still have!!!) a dream to be top of the world on something. But till now what I have gained or done is "void".

I am now in such an institute that never been in World Final of ACM-ICPC. More over we have only 4 serious contest programmers among 800 students!! Let me not talk about the facilities. Still we are striving for success.

All of these are excuses, nothing else. May be I could do same or even better if I was in their place who are now top of the world (I am actually joking!!). But the world is not going to compromise for me, or will it? I may console myself that I didn't get much support or bla bla bla but that's not going to solve anything. I can participate in ACM-ICPC regional for three more times. So all I need to do is to keep working harder than anyone and I am trying. Wish me luck.

Thanks for reading :)
