Answer 1

If container is vector, you can use swap to release memory, container is deque, you should use clear to release memory, like this:

int main ()
{
    deque deq;
    for(int i = 0; i < 100; ++i)
    {
        Node tmp;
        tmp.vec.resize(100000);
        deq.push_back(tmp);
    }
    while(!deq.empty())
    {
        deq.pop_front();
    }
    deq.clear();
    // Or, you should try to use `deque().swap(deq);`, not `local`.

    cout<<"releas\n";
    sleep(80000000);
    return 0;
}
