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>
int main(void)
{
    int h, w, i;
    scanf("%d%d", &h, &w);

    char a[100][100];

    for(i=0; i<h; i++){
        scanf("%s", a[i]);
    }
    for(i=0; i<w+2; i++)
        putchar('#');
    putchar('\n');

    for(i=0; i<h; i++)
        printf("#%s#\n", a[i]);

    for(i=0; i<w+2; i++)
        putchar('#');
    putchar('\n');
    return 0;
}
