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.

Examples

Input

Output

z#

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {

	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		// 整数の入力
		// スペース区切りの整数の入力
		int a = sc.nextInt();
		int b = sc.nextInt();
		int c = b + 2;
		
		String stArray[] = new String[a];
		for (int i = 0; i < a;i ++ ){
				
				stArray[i] = sc.next();
		}

		String s = "";
		
		for (int i = 0; i < c ;i ++ ){
			s = s + "#" ;
		}
		System.out.println(s);
		
		String t = "";		
		for (int i = 0; i < a ;i ++ ){
			t = t + "#" + stArray[i] + "#" ;
			System.out.println(t);
			t = "" ;
		}
		System.out.println(s);

	}
