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>
#include <string.h>

int main(int argc, char *argv[])
{
    int i, H, W;
    char buf[256], *p;
    scanf("%d %d\n", &H, &W);
    for ( i = 0; i < W+2; i++ ){
        printf("#");
    }
    printf("\n");
    for ( i = 0; i < H; i++ ){
        fgets(buf, sizeof(buf), stdin);
        p = strchr(buf, '\n');
        *p = '#';
        printf("#%s\n", buf);
    }
    for ( i = 0; i < W+2; i++ ){
        printf("#");
    }
    printf("\n");
    return 0;
