Choose Two Numbers
Description
You are given an array $A$, consisting of $n$ positive integers $a_1, a_2, \dots, a_n$, and an array $B$, consisting of $m$ positive integers $b_1, b_2, \dots, b_m$.
Choose some element $a$ of $A$ and some element $b$ of $B$ such that $a+b$ doesn't belong to $A$ and doesn't belong to $B$.
For example, if $A = [2, 1, 7]$ and $B = [1, 3, 4]$, we can choose $1$ from $A$ and $4$ from $B$, as number $5 = 1 + 4$ doesn't belong to $A$ and doesn't belong to $B$. However, we can't choose $2$ from $A$ and $1$ from $B$, as $3 = 2 + 1$ belongs to $B$.
It can be shown that such a pair exists. If there are multiple answers, print any.
Choose and print any such two numbers.
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 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.
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.

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.
