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

2 3
abc

Solution:
import java.util.*;
public class Main{
	public static void main(String[] args){
    	Scanner sc = new Scanner(System.in);
      int h = sc.nextInt();
      int w = sc.nextInt();
      char[][] a = new char[h+1][];
      for(int i = 0;i < h;i++){
        	a[i] = sc.next().toCharArray();
      }
  	  for(int i = 0;i < w+2;i++){System.out.print('#');}
      System.out.println("");
      for(int i = 0;i < h;i++){
        System.out.print('#');
      	for(int j = 0;j < w;j++){
        	System.out.print(a[i][j]);
        }
        System.out.print('#');
        System.out.println("");
      }
      
      for(int i = 0;i < w+2;i++){System.out.print('#');}
    }
