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

int W=in.nextInt();
String dum=in.nextLine();
String s[]=new String[H];
for (int i=0; i<H; i++)
s[i]=in.nextLine();
for(int i=0; i<W+2; i++)
System.out.print("#");
System.out.println("");
for (int i=0; i<H; i++)
System.out.println("#"+s[i]+"#");
for(int i=0; i<W+2; i++)
System.out.print("#");
