Problem: You are given a image with a height of H pixels and a width of W pixels. Each pixel is represented by a lowercase English letter. The pixel at the i-th row from the top and j-th column from the left is a_{ij}.

Put a box around this image and output the result. The box should consist of `#` and have a thickness of 1.

Constraints

* 1 ≤ H, W ≤ 100
* a_{ij} is a lowercase English letter.

Input

Input is given from Standard Input in the following format:


H W
a_{11} ... a_{1W}
:
a_{H1} ... a_{HW}


Output

Print the image surrounded by a box that consists of `#` and has a thickness of 1.

Solution (in JAVA):

Solution:
import java.util.*;
// warm-up
public class Main {

	static void solve() {
		Scanner sc = new Scanner(System.in);
		int r = sc.nextInt(), c = sc.nextInt(), n=r;
		System.out.println("#"+"#".repeat(c)+"#");
		while (n-->0) System.out.println("#"+sc.next()+"#");
		System.out.println("#"+"#".repeat(c)+"#");
		sc.close();		
	}

	public static void main(String args[]) {
		solve();
	}
