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.

Sample Input 1

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>
int main()
{
	int a,b,c,d,h,w,e=0,f=0;
	char space;
	while(scanf("%d%d",&h,&w)!=EOF)
	{
		getchar();
		char pic[10000][10000];
		int n,m;
		n=h;m=w;
		while(n--)
		{
			scanf("%s",pic[f]);
			f++;
		}
		f=0;
	    for(a=0;a<w+2;a++)
		{
			printf("#");
		}
		printf("\n#");
		e=0;
		for(b=0;b<h;b++)
		{
			printf("%s",pic[e]);
			printf("#\n#");
			e++;
		}
		for(c=0;c<w;c++)
		{
			printf("#");
		}
		printf("#\n");
	}
