Generic remove

template <class T>
void remove(std::vector<T>& v, int pos){
    std::vector<T>::iterator it = v.begin();
    std::advance(it, pos);
    v.erase(it);
}

template <class T>
void remove(std::vector<T>& v, int pos){
    v.erase(v.begin()+pos);
}

//or why not a swap-n-pop?
template<typename T>
void erase(std::vector<T>& v, int pos){
    std::swap(v[pos], v.back());
    v.pop_back();
}
