using System;
class Program
{
	static void Main(string[] args)
	{
      string[] input = Console.ReadLine().Split(' ');
      int H = int.Parse(input[0]);
      int W = int.Parse(input[1]);
      string[] a = new string[H];
      for (int i=0; i<H; i++)
      {
        a[i] = Console.ReadLine();
      }
      string tmp = new string('#', W+2);
      Console.WriteLine(tmp);
      for (int i=0; i<H; i++)
      {
        Console.WriteLine("#" + a[i] + "#");
      }
      Console.WriteLine(tmp);
    }
