Binary search

A sorted array of $n$ integers is given. It is necessary to answer $q$ queries: whether the given number $x$ is present in the array.

Input

The first line contains two integers $n$ and $q(n,q\le 10^6)$. The second line contains $n$ integers sorted in ascending order. Each of the following $q$ lines contains one number $x$. All numbers in the array do not exceed $10^9$ by absolute value.

Output

For each query, print "YES" on a separate line if the number $x$ is present in the array, and "NO" otherwise.
