### Prompt

Create a solution in cpp for the following problem:

Find the difference of two sets $A = \\{a_0, a_1, ..., a_{n-1}\\}$ and $B = \\{b_0, b_1, ..., b_{m-1}\\}$, $A - B$.

Constraints

* $1 \leq n, m \leq 200,000$
* $0 \leq a_0 < a_1 < ... < a_{n-1} \leq 10^9$
* $0 \leq b_0 < b_1 < ... < b_{m-1} \leq 10^9$

Input

The input is given in the following format.


$n$
$a_0 \; a_1 \; ... \; a_{n-1}$
$m$
$b_0 \; b_1 \; ... \; b_{m-1}$


Elements in $A$ and $B$ are given in ascending order. There are no duplicate elements in each set.

Output

Print elements in the difference in ascending order. Print an element in a line.

Example

Input

5
1 2 3 5 8
2
2 5


Output

1
3
8

### Response

```cpp
#include <bits/stdc++.h>

    std::deque<int> result;
    int n,a,m,b;
    cin >> n;
    for (int i=0;i<n;i++) {
        cin >> a;
        deq_a.emplace_back(a);
    }
    cin >> m;
    for (int j=0;j<m;j++) {
        cin >> b;
        deq_b.emplace_back(b);
    }
    set_difference(deq_a.begin(),deq_a.end(),deq_b.begin(),deq_b.end(),inserter(result,result.end()));
    for (int k=0;k<result.size();k++) {
        cout << result[k] << endl;
    }
}
