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

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int h = sc.nextInt();
		int w = sc.nextInt();

		String[] strs  = new String[h];

		for (int i = 0; i < h;i++){
			strs[i] = sc.next();
		}

		StringBuilder sb =new StringBuilder();
		// up/down bar
		for(int i = 0; i < (w+2); i++){
			sb.append('#');
		}
		String  updown= new String(sb);

		// display
		System.out.println(updown);
		for(int i=0; i < h;i++){
			System.out.print("#");
			System.out.print(strs[i]);
			System.out.println("#");
		}
		System.out.println(updown);

		sc.close();
	}
}
