store vector in another vector c 2b 2b

1    Input:
2    vector<int> v1{ 10, 20, 30, 40, 50 };
3    vector<int> v2{ 100, 200, 300, 400 };
4
5    //appending elements of vector v2 to vector v1
6    v1.insert(v1.end(), v2.begin(), v2.end());
7
8    Output:
9    v1: 10 20 30 40 50 100 200 300 400
10    v2: 100 200 300 400
