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
arc


Output

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


Input

1 1
z

Solution (in JAVA):

Solution:

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner s = new Scanner(System.in);
		StringBuilder sb = new StringBuilder("");
		int h = s.nextInt();
		int w = s.nextInt();
		int i = 0;
		String a = "";
		String b = "";

		String ary[] = new String[h];
		for (i = 0; i < h; i++) {
			ary[i] = "#" + s.next() + "#";

		}
		String ary1[] = new String[w + 2];

		for (i = 0; i < w + 2; i++) {
			ary1[i] = "#";

			a = a + ary1[i];

		}
		System.out.println(a);
		for (i = 0; i < h; i++) {
			System.out.println(ary[i]);
		}
		System.out.println(a);

	}
