package main

import "fmt"
import "strings"

func f(s string, n int) {
	for i := 0; i < n; i++ {
		fmt.Print(s)
	}
	fmt.Println()
}

func main() {
	var h, w int
	fmt.Scan(&h, &w)
	f("#", w+2)
	for i := 0; i < h; i++ {
		var s string
		fmt.Scan(&s)
		s = strings.TrimSpace(s)
		fmt.Print("#")
		fmt.Print(s)
		fmt.Println("#")
	}
	f("#", w+2)
