What will be the output of the following C++ code?
#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main ()
{
int first[] = {5, 10, 15};
int second[] = {50, 40, 30};
vector<int> v(4);
vector<int> :: iterator it;
sort (first, first + 3);
sort (second, second + 3);
it = set_symmetric_difference (first, first + 2, second, second + 2,
v.begin());
v.resize(it - v.begin());
for (it = v.begin(); it != v.end(); ++it)
cout << ' ' << *it;
return 0;
}
