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) {
		// TODO 自動生成されたメソッド・スタブ
		Scanner s = new Scanner(System.in);
		int H = s.nextInt();
		int W = s.nextInt();

		char[][] arrays = new char[H][W];

		for (int i = 0; i < H; i++) {
			arrays[i] = s.next().toCharArray();
		}
		for (int i = 0; i < H + 2; i++) {
			if (i == 0 || i == H + 1) {
				for (int j = 0; j < W + 2; j++) {
					System.out.print("#");
				}
			} else {
				for (int j = 0; j < W + 2; j++) {
					if (j == 0 || j == W + 1) {
						System.out.print("#");
					} else {
						System.out.print(arrays[i - 1][j - 1]);
					}
				}
			}
			System.out.print("\n");
		}
	}
