Sorted array of n integers is given. You must answer q queries: whether the given number x is in the array.
First line contains two numbers n and q(n,q≤106). Second line contains n integers sorted in increasing order. Each of the next q lines contains value of x. The numbers in array do not exceed 109 by absolute value.
For each value of x print on a separate line "YES" if x is present in array and "NO" otherwise.
