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

Solution (in JAVA):

Solution:
import java.util.Scanner;
 
class Main {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
 
    int H = sc.nextInt();
    int W = sc.nextInt();
 
    for(int i = 0; i <= W; i++) {
        System.out.print("#");
    }
    System.out.println("#");
 
    for(int j = 0; j < H; j++) {
        System.out.print("#");
        System.out.print(sc.next());
        System.out.println("#");
    }   
 
     for(int i = 0; i <= W; i++) {
        System.out.print("#");
    }
        System.out.println("#");
  }
