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:
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();
      String a[] = new String[H];
      String lst = "";
      for (int j = 0; j < W+2 ; j++) {
        lst += "#";
      }
      System.out.println(lst);
      for (int i = 0; i < H ; i++) {
        a[i] = sc.next();
        System.out.println("#" + a[i] + "#");
      }
      System.out.println(lst);
  }
