问题：

開始直接用输入的数作为宽和高，但实际上要多出两行边框，所以要加一个2。

还有题目要求最后要输出一个空行没有注意到。

Problem Description

Give you the width and height of the rectangle,darw it.

Input

Input contains a number of test cases.For each case ,there are two numbers n and m (0 < n,m < 75)indicate the width and height of the rectangle.Iuput ends of EOF.

Output

For each case,you should draw a rectangle with the width and height giving in the input.

after each case, you should a blank line.

Sample Input

3 2

Sample Output

+---+

import java.util.*;

public class Main{
	public static void n1(int t){

				s=s+"+";
			else
				s=s+"-";
		}
		System.out.println(s);
	}
	public static void n2(int t){
		String s="";
		for(int i=1;i<=t;i++){
			if(i==1||i==t)
				s=s+"|";
			else
				s=s+" ";
		}
		System.out.println(s);
	}
	public static void main(String[] args) {
		Scanner cin=new Scanner(System.in);
		while(cin.hasNext()){
			int n=cin.nextInt();
			int m=cin.nextInt();
			int t=n+2;
			for(int i=0;i<m+2;i++){
				if(i==0||i==m+1)
					n1(t);
				else
					n2(t);
			}
			System.out.println();
		}
