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}

Solution in C (Clang 3.8.0) (judge verdict: Accepted)

#include <stdio.h>
int main(void){
    int h,w,i,j;
    char gomi;
    scanf("%d %d",&h,&w);
    char data[h][w];
    scanf("%c",&gomi);
    for(i=0;i<h;i++){
        for(j=0;j<w;j++){
            scanf("%c",&data[i][j]);
            if(j==w-1){
                scanf("%c",&gomi);
            }
        }
    }
    for(i=0;i<w+2;i++){
        printf("#");
    }
    printf("\n");
    for(i=0;i<h;i++){
        for(j=0;j<w;j++){
            if(j==0){
                printf("#");
            }
            printf("%c",data[i][j]);
            if(j==w-1){
                printf("#\n");
            }
        }
    }
    for(i=0;i<w+2;i++){
        printf("#");
