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

#####


Input

1 1
z


Output

z#

Solution (in JAVA):

Solution:
import java.util.Scanner;
public class Main {
	public static void main(String[] args) throws Exception {
		Scanner sc = new Scanner(System.in);
		String[] hw = sc.nextLine().split(" ");
		int h = Integer.parseInt(hw[0]) + 1;
		int w = Integer.parseInt(hw[1]) + 2;

		for (int i = 0; i <= h; i++) {
			if (i == 0 || i == h) {
				System.out.println(new String(new char[w]).replace("\0", "#"));
			}else {
				System.out.println("#" + sc.nextLine() + "#");
			}
		}
	}
