main()
{
   int n, m, i, j;
   char a[100];
   while(scanf("%d%d",&n,&m)!=EOF)
   {
       getchar();
       for(i=0;i<n;i++)
       {
           scanf("%s",&a[i]);
       }
       for(j=0;j<m+2;j++)
       printf("#");
       printf("\n");
       for(i=0;i<n;i++)
       {
           printf("#%s#",a[i]);
       }
       for(i=0;i<m+1;i++)
       printf("#");
