using System;

namespace ABC062

    class Program
    {
        static void Main(string[] args)
        {
            var groupA = new[] { 1, 3, 5, 7, 8, 10, 12 };
            var groupB = new[] { 4, 6, 9, 11 };

            var s = Console.ReadLine().Split(' ');
            var h = int.Parse(s[0]);
            var w = int.Parse(s[1]);

            Console.WriteLine(new string('#', w + 2));

            for (var i = 0; i < h; i++)
            {
                Console.Write('#');
                Console.Write(Console.ReadLine());
                Console.WriteLine('#');
            }

            Console.WriteLine(new string('#', w + 2));
