First line is the number of test cases T(T<=8).
T lines follow, each line includes an integer N(N<=7), and you should help C(N) to sign his name.
OutputC0’s signature is ‘C’.
When you draw C(N)’s name, you should print the name using C(N-1)’s name as its element, and using the following format to draw it.
*XX
X**
*XX
(X is the element, * is blank space)
And please don’t print extra spaces at the end of line.
For example, C1’s name should be
*CC *CC
C C**
*CC But not *CC
(I use * to show you where are spaces.)
