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.

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

#include <stdio.h>

char a[105][105];

int main(){

	int H,W;

	scanf("%d %d",&H,&W);

	int i,j;

	for(i=0;i<H;i++){
		for(j=0;j<W;j++){
		scanf(" %c",&a[i][j]);
		}
	}

	for(i=0;i<H+2;i++){
		for(j=0;j<W+2;j++){
			if(i==0 || i==H+1 || j==0 || j==W+1){printf("#");}
			else{printf("%c",a[i-1][j-1]);}
		}
		printf("\n");
	}


	return 0;
