Problem Statement

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 MainApp
{
    static public void Main(string[] args)
    {
        var read = Console.ReadLine();
        var split = read.Split(' ');
        int H = int.Parse(split[0]);
        int W = int.Parse(split[1]);
        string outputsharp = "";
        for (int c = 0; c < W + 2; c++)
        {
            outputsharp += "#";
        }
        Console.WriteLine(outputsharp);
        for (int c = 0; c < H; c++)
        {
            read = Console.ReadLine();
            string output = "#" + read + "#";
            Console.WriteLine(output);
        }
        Console.WriteLine(outputsharp);
    }
