Thank's everybody to yours answers. But, my problem is described below. I have this problem:
In somewhere have a finite number set where all its elements are natural numbers. Well, this numeric set is defined here by N. I have two others sets number (R and D), where R is a subset of N and R # N, and S is a subset of N and S # N, and R # D. Think me, if a person 'a' have Ra and Da (where Ra and Da is numerical subset of N) and another person 'b' have Rb and Db (where Rb and Db is a numerical subset of N too). That's ok ? Now, I want to know which elements in intersection between Di and R(i+1). But this is a small case of a real case I need to resolve. In Real case, I have a group of people P that, each element p in P have two sets numerical (Ri and Di, where i is a ith element of P). You see my problem ? I think that, if I use the backtracking algorithm that I can to resolve this problem into a O(n) analysis. What do You think about this ? regards, Luciano Pinheiro. 2008/11/4 Rahul Singhal <[EMAIL PROTECTED]>: > there ia a book called "FUNDAMENTALS OF DATA STRUCTURES BY HOROWITZS AND > SAHNI". > > NOTE:There are two versions of it.The ebook of the version containing this > topic is not available as per knowlegde but it is available in market.This > version's size is long as compare to other version. > This topic is nicely presented in that book with the help of examples and > some good exercise questions at the end of the chapter > > On Tue, Nov 4, 2008 at 10:12 AM, Luciano Pinheiro <[EMAIL PROTECTED]> > wrote: >> >> Please, help me people ! >> >> I need understand and develop a backtracking algorithm to include into >> a program and I don't nkow where find these. >> >> Someone have any document, or URL to indicate to me ? >> >> Sincerely, >> >> ---------------------------------------- >> Luciano Soares Pinheiro Jr. >> Analista desenvolvedor Sr. >> >> > > > > -- > Rahul singhal > B.Tech.
