Deal with C++ Comments

In C++ ,there are two styles of comment, one is a stream of characters enclosed by "/*" and "*/", and the other is a single line beginning with "//". Comments will not be nested as in c++.
Your task is to deal with these comments, which is to capitalize all the letters in a comment and count the number of occurrence of comments.

To simplify your task, you may assume that comments will not appear in constant strings.

Input

The first line speicifies the number of test cases T (T <= 10). Each test case begins with a number L (L <= 10000), the number of lines of the C++ code, following L lines which is the body of the code.

Output

For each test case, output the number occurrence of comments you've found and then the resulting text of your processing. print a line after each test case.

Sample Input

3

1
/*aoao~~
1
/*aoao //aoao /
1
i=0;do/*kaka
/i++ while(i--); // this is an infinite loop

Sample Output

0
/*aoao~~

1
/*AOAO //AOAO */

2
i=0;do/*KAKA*/i++ while(i--); // THIS IS AN INFINITE LOOP
