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(void)
{
	int h,w;
	while(scanf("%d %d",&h,&w)!=EOF)

		char s[101][101]={0};
		char q[101];
		for(i=1;i<=h;i++)
		{
			char q[101]={0};
			scanf("%s",&q);
			for(j=1;j<=w;j++)
			{
				s[count][j]=q[j-1];
			}
			count++;
		}
		for(i=1;i<=w+2;i++)
		printf("#");
		printf("\n");
		for(i=1;i<count;i++)
		{
			printf("#");
