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>
int main(){
    int h,w;
    int i,j;
    char a[101][101];
    scanf("%d%d",&h,&w);
    getchar();
    for(i = 0; i < h; i++){
        for(j = 0; j < w; j++){
            scanf("%c",&a[i][j]);
        }
        getchar();
    }
    for(i = -1; i < h+1; i++){
        for(j = -1; j < w+1; j++){
            if(i==-1||i==h)printf("#");
            else if(j==-1||j==w)printf("#");
            else printf("%c",a[i][j]);
        }
        putchar('\n');
    }
    return 0;
