# Digit Size

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.

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).
