What is the best way to delete elements from a vector given an another vector?
I have come up with the following code:
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
void remove_elements(vector<int>& vDestination, const vector<int>& vSource)
{
if(!vDestination.empty() && !vSource.empty())
{
for(auto i: vSource) {
vDestination.erase(std::remove(vDestination.begin(), vDestination.end(), i), vDestination.end());
}
}
}
int main()
{
vector<int> v1={1,2,3};
vector<int> v2={4,5,6};
vector<int> v3={1,2,3,4,5,6,7,8,9};
remove_elements(v3,v1);
remove_elements(v3,v2);
for(auto i:v3)
cout << i << endl;
return 0;
}
Here the output will be:
7
8
9
