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()
{
	int n,m,i,j;
	char a[101][101];
	while(scanf("%d %d\n",&n,&m)!=EOF)
	{
		for(i=0;i<n;i++)
		{
		for(j=0;j<m;j++)
		{
			scanf("%c",&a[i][j]);
		
		}
		getchar();
}
for(i=0;i<m+2;i++)
{
printf("#");}
printf("\n");
for(i=0;i<n;i++)
{

printf("#");
