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.

public class Main {
    public static void main(String[] args) {
        List<String> list = new ArrayList<String>();
        Scanner sc = new Scanner(System.in);
        int h = sc.nextInt();
        int w = sc.nextInt();
        String li0 = "";
        for(int i = 0; i < w; i++){
            li0 += "#";
        }
        list.add(li0);
        
        for(int i = 0; i < h; i++){
            String s = sc.next();
            list.add(s);
        }
        list.add(li0);

        for(int i = 0; i < list.size(); i++){
            System.out.println("#" + list.get(i) + "#");
        }
    }
