Choose Two Numbers

Description:

Input:

The first line contains one integer $$$n$$$ ($$$1\le n \le 100$$$) — the number of elements of $$$A$$$.

The second line contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le 200$$$) — the elements of $$$A$$$.

The third line contains one integer $$$m$$$ ($$$1\le m \le 100$$$) — the number of elements of $$$B$$$.

The fourth line contains $$$m$$$ different integers $$$b_1, b_2, \dots, b_m$$$ ($$$1 \le b_i \le 200$$$) — the elements of $$$B$$$.

It can be shown that the answer always exists.

Output:

Output two numbers $$$a$$$ and $$$b$$$ such that $$$a$$$ belongs to $$$A$$$, $$$b$$$ belongs to $$$B$$$, but $$$a+b$$$ doesn't belong to nor $$$A$$$ neither $$$B$$$.

If there are multiple answers, print any.

Sample Input:

1
20
2
10 20

Sample Output:

20 20

Sample Input:

3
3 2 2
5
1 5 7 7 9

Sample Output:

3 1

Sample Input:

4
1 3 5 7
4
7 5 3 1

Sample Output:

1 1

Note:

In the first example, we can choose $$$20$$$ from array $$$[20]$$$ and $$$20$$$ from array $$$[10, 20]$$$. Number $$$40 = 20 + 20$$$ doesn't belong to any of those arrays. However, it is possible to choose $$$10$$$ from the second array too.

In the second example, we can choose $$$3$$$ from array $$$[3, 2, 2]$$$ and $$$1$$$ from array $$$[1, 5, 7, 7, 9]$$$. Number $$$4 = 3 + 1$$$ doesn't belong to any of those arrays.

In the third example, we can choose $$$1$$$ from array $$$[1, 3, 5, 7]$$$ and $$$1$$$ from array $$$[7, 5, 3, 1]$$$. Number $$$2 = 1 + 1$$$ doesn't belong to any of those arrays.
