Problem Description Little Q likes solving math problems very much. Unluckily, however, he does not have good spatial ability. Everytime he meets a 3D geometry problem, he will struggle to draw a picture.
Now he meets a 3D geometry problem again. This time, he doesn‘t want to struggle any more. As a result, he turns to you for help.
Given a cube with length a

, width b and height c, please write a program to display the cube.

Input The first line of the input contains an integer T(1≤T≤50), denoting the number of test cases.
In each test case, there are 3 integers a,b,c(1≤a,b,c≤20), denoting the size of the cube.

Output For each test case, print several lines to display the cube. See the sample output for details.

Sample Input 2 1 1 1 6 2 4

思路：

　　模擬題，先用‘’.‘’填充所有的，然後先填頂面，再填正面，最後填側面。題目不難，但是有些復雜，所以要細心，註意分類討論，註意邊界的情況。

代碼：
