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.

int main(){
    char ch[105][105];
    int n,m;
    scanf("%d%d",&n,&m);
    getchar();
    for(int i=0;i<n;i++) gets(ch[i]);
    for(int i=0;i<strlen(ch[0])+2;i++) printf("#");
    putchar('\n');
    for(int i=0;i<n;i++){
        putchar('#');
        for(int j=0;j<strlen(ch[i]);j++) printf("%c",ch[i][j]);
        putchar('#');
        putchar('\n');
    }
    for(int i=0;i<strlen(ch[0])+2;i++) printf("#");
    return 0;
