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 Python (3.4.3) (judge verdict: Accepted)

H, W = map(int, input().split())
pic = [[i for i in input()] for j in range(H)]
ans = [["#" for i in range(W+2)] for j in range(H+2)]

for h in range(H):
    for w in range(W):
        ans[h+1][w+1] = pic[h][w]
        
for i in range(H+2):
    for j in range(W+2):
        print(ans[i][j], end="")
    print()
