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: Wrong Answer)

#include<stdio.h>
#include<string.h>
int main()
{
int h,w,i,j;
char a[100][100];
scanf("%d%d",&h,&w);
for(i=0;i<h;i++)
gets(a[i]);
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("%s",a[i-1]);
}
printf("\n");
}
return 0;
