A friend of yours has just bought a new computer. Before this, the most powerful machine he ever used was a pocket calculator. He is a little disappointed because he liked the LCD display of his calculator more than the screen on his new computer! To make him happy, write a program that prints numbers in LCD display style.

Description
Input
The input file contains several lines, one for each number to be displayed. Each line contains integers s and n, where n is the number to be displayed ( 0n99, 999, 999) and s is the size in which it shall be displayed ( 1s10). The input will be terminated by a line containing two zeros, which should not be processed
Output
Print the numbers specified 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, including the last digit. There must be exactly one column of blanks between two digits. Output a blank line after each number. You will find an example of each digit in the sample output below.
Sample Input
2 12345
3 67890

HINT
模拟题。这道题是在控制台中以计算器的显示形式显示指定尺寸大小的一串数字。
我的做法是提前写好数字的模板（因为尺寸不确定，所以要把数字做成模板），存放在一个三维数组中（数字，行，列）。输入尺寸和数字串后，将数字的模板组合起来，然后解析成指定尺寸的数字输出出来。
My code：
