题目描述
You are given a sequence of numbers $a_{1},a_{2},...,a_{n}$ , and a number $m$ .
Check if it is possible to choose a non-empty subsequence $a_{ij}$ such that the sum of numbers in this subsequence is divisible by $m$ .
Check if it is possible to choose a non-empty subsequence $a_{ij}$ such that the sum of numbers in this subsequence is divisible by $m$ .
输入格式
The first line contains two numbers, $n$ and $m$ ( $1<=n<=10^{6}$ , $2<=m<=10^{3}$ ) — the size of the original sequence and the number such that sum should be divisible by it.
The second line contains $n$ integers $a_{1},a_{2},...,a_{n}$ ( $0<=a_{i}<=10^{9}$ ).
The second line contains $n$ integers $a_{1},a_{2},...,a_{n}$ ( $0<=a_{i}<=10^{9}$ ).
输出格式
In the single line print either "YES" (without the quotes) if there exists the sought subsequence, or "NO" (without the quotes), if such subsequence doesn't exist.

In the first sample test you can choose numbers $2$ and $3$ , the sum of which is divisible by $5$ .
In the second sample test the single non-empty subsequence of numbers is a single number $5$ . Number $5$ is not divisible by $6$ , that is, the sought subsequence doesn't exist.
In the third sample test you need to choose two numbers $3$ on the ends.
In the fourth sample test you can take the whole subsequence.

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。
确定要清空代码吗？
