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

Output

#####
#abc#
#arc#
#####


Input

1 1
z


Output

z#

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();

        String[] ans = new String[h + 2];

        for (int i = 0; i < h + 2; ++i) {
            ans[i] = "";
        }

        for (int i = 0; i < w + 2; ++i) {
            ans[0] += "#";
            ans[h+1] += "#";
        }

        for (int i = 1; i < h + 1; ++i) {
            ans[i] += "#";
            ans[i] += sc.next();
            ans[i] += "#";
        }

        for (int i = 0; i < h + 2; ++i) {
            System.out.println(ans[i]);
        }
    }
