# Problem D

Prime Sieve

## Input

The first line of input consists of two integers $n$, $q$, where $1 \leq n \leq 10^8$ and $1 \leq q \leq 20000$. Then follow $q$ lines, each containing an integer $x$ satisfying $1 \leq x \leq n$.

## Output

On the first line of output, write one line giving the number of prime numbers less than or equal to $n$. Then for each query $x$, output $1$ if $x$ is a prime and ouput $0$ if $x$ is composite.
