问题描述

A friend of you has just bought a new computer. Until now, the most powerful computer he ever used has been a pocket calculator. Now, looking at his new computer, he is a bit disappointed, because he liked the LC-display of his calculator so much. So you decide to write a program that displays numbers in an LCD-display-like style on his computer

输入描述

The input file contains several lines, one for each number to be displayed. Each line contains two integers s, n (1<=s<=10,0<=n<=99,999,999 ), where n is the number to be displayed and s is the size in which it shall be displayed.

The input file will be terminated by a line containing two zeros. This line should not be processed.

输出描述

Output the numbers given in the input file in an LCD-display-style using s "-" signs for the horizontal segments and s "|" signs for the vertical ones. Each digit occupies exactly s+2 columns and 2s+3 rows. (Be sure to fill all the white space occupied by the digits with blanks, also for the last digit.) There has to be exactly one column of blanks between two digits.

Output a blank line after each number. (You will find a sample of each digit in the sample output.)

问题分析：

首先需要一个字模数组，然后进行放大。

每行有多个字，同时需要考虑放大后行数会增加。

需要注意，每组数据后有一个空行，每个数字后有一个空格，每一行后面多一个空格（特殊的地方，需要注意）。

程序说明：

（略）

题记：

显示到处都有，字符显示已经很少见。

AC的C++程序如下：

#include <iostream>
#include <cstdio>
#include <cstring>

using namespace std;

        " - "
