题目描述
You are given two lists of non-zero digits.
Let's call an integer pretty if its (base $10$ ) representation has at least one digit from the first list and at least one digit from the second list. What is the smallest positive pretty integer?

输入格式
The first line contains two integers $n$ and $m$ ( $1<=n,m<=9$ ) — the lengths of the first and the second lists, respectively.
The second line contains $n$ distinct digits $a_{1},a_{2},...,a_{n}$ ( $1<=a_{i}<=9$ ) — the elements of the first list.
The third line contains $m$ distinct digits $b_{1},b_{2},...,b_{m}$ ( $1<=b_{i}<=9$ ) — the elements of the second list.

In the first example $25$ , $46$ , $24567$ are pretty, as well as many other integers. The smallest among them is $25$ . $42$ and $24$ are not pretty because they don't have digits from the second list.
In the second example all integers that have at least one digit different from $9$ are pretty. It's obvious that the smallest among them is $1$ , because it's the smallest positive integer.

你好，我是作答助手。可以问思路、复杂度、样例含义或代码报错原因；不会直接给出完整 AC 代码。
