Question

Given two vectors of integers, how to determinate if there’s some element from 1st vector is present in 2nd one?

Answer 1

I guess something like this should work:

std::vector<int> v1,v2;
if(std::find_first_of(v2.begin(),v2.end(),v1.begin(),v1.end()) != v2.end())
   std::cout << "found!\n";
