题目描述
Digital LC-display is widely used in many different fields such as electronic calculator, electronic watch, digital instruments, etc. A simulated example of the numbers represented by digital LC-display device is shown as follows:
Each number represented by LC-display above is composed of s "-" signs for the horizontal segments and s "|" signs for the vertical ones, and each number exactly occupies s+2 columns and 2s+3 rows. Your task is to change the size of the original numbers by changing "s" — the number of signs.
输入
The first line of input contains a number t, which means there are t cases of the test data.
The input contains several lines, 2s + 4 for each number to be displayed. The first line of each case contains two integer s and t (1 <= s, t <= 9), where s is the original size of the numbers and t is the target size of numbers that you should output. The following 2s + 3 lines show the original number n (the digit of n will not exceed 9) you should deal with. Each digit of n will be separated by an empty column (except for the last digit).
输出
For each test case, output the case number and then output the target number according to the input. Output a blank line after each case.
