Hello, assume that we have a data1 and data2. How can I intersect them with std::set_intersect()? struct pID { int ID; unsigned int IDf;// postition in the file pID(int id,const unsigned int idf):ID(id),IDf(idf){} bool operator<(const pID& p)const { return ID<p.ID;} }; struct ID{}; struct IDf{}; typedef mul...
Not used set_intersection before, but I believe it will work with maps. I wrote the following example code but it doesn't give me what I'd expect: #include <map> #include <string> #include <iostream> #include <algorithm> using namespace std; struct Money { double amount; string currency; bool operator< ( const Money& rhs ...
Suppose I have the array int a[] = new int[] { 0xBCDA, 0xABFE, 0xBCAD, 0xEFCA, 0xFFCA } I know that there is always some hexadecimal number which occurs in all number or in this case A is repeated in the array everywhere so my aim is print only the repeated number and other numbers should be zero, so my new array should be like thi...
I spent a considerable amount of time coding in Baeza-Yates' fast set intersection algorithm for one of my apps. While I did marginally out-do the STL set_intersect, the fact that I required the resultant set to be sorted removed any time I had gained from implementing my own algorithm after I sorted the output. Given that the STL set_in...
