You are given an array $$a$$ of size $$n$$ consisting of integers. Now, you need to find the number of distinct integers x, such that there exists a sequence of distinct indices  \(i_1 < i_2 <... < i_m , 1 \le m \le k \)  and   \(a[i_1] \space or \space a[i_2] \space or \space...\space or \space a_[i_m]=x\)

Here or represents the bitwise OR operator.  

Input

First line of the each input will contain two space seperated integers $$n$$ and $$k$$ denoting the size of the array and maximum size of the subset, respectively.

Next line will contain $$n$$ spaced integers denoting elements of the array.

Constraint

\(1 \le n \le 1000\)

\(1 \le k \le 20\)

\(1 \le a[i] \le 2047\)

Output

Output will consists of a single integer denoting the number of unique integers that can be formed by taking Bitwise OR  of every subset of size less than or equal to $$k$$.
