Solve the programming task below in a Python markdown code block.
In the current semester, you have taken X RTP courses, Y Audit courses and Z Non-RTP courses. 

The credit distribution for the courses are:
4 credits for clearing each RTP course.
2 credits for clearing each Audit course.
No credits for clearing a Non-RTP course. 

Assuming that you cleared all your courses, report the number of credits you obtain this semester.

------ Input Format ------ 

The first line contains a single integer T, the number of test cases. T test cases follow. Each test case consists of one line, containing 3 integers separated by spaces.
- The first integer is X, the number of RTP courses.
- The second integer is Y, the number of Audit courses.
- The third integer is Z, the number of non-RTP courses.

------ Output Format ------ 

The output must consist of T lines. The i^{th} should consist of a single integer: the number of credits one gets for the i^{th} test case.

------ Constraints ------ 

$1 ≤T ≤10$
$1 ≤X, Y, Z ≤10$

Test case $1$: You obtain $4$ credits for each of the RTP courses, accounting for $4 \cdot 6 = 24$ credits. You also obtain $2$ credits for each audit course, accounting for $2 \cdot 6 = 12$ credits. Finally, you get $0$ credits for each of the non-RTP courses, accounting for $0 \cdot 5 = 0$ credits. This accounts for a total of $24 + 12 + 0 = 36$ credits.

Test case $2$: You obtain $4$ credits for each of the RTP courses, accounting for $4 \cdot 8 = 32$ credits. You also obtain $2$ credits for each audit course, accounting for $2 \cdot 7 = 14$ credits. Finally, you get $0$ credits for each of the non-RTP courses, accounting for $0 \cdot 2 = 0$ credits. This accounts for a total of $32 + 14 + 0 = 46$ credits.

Test case $3$: You obtain $4$ credits for each of the RTP courses, accounting for $4 \cdot 9 = 36$ credits. You also obtain $2$ credits for each audit course, accounting for $2 \cdot 3 = 6$ credits. Finally, you get $0$ credits for each of the non-RTP courses, accounting for $0 \cdot 8 = 0$ credits. This accounts for a total of $36 + 6 + 0 = 42$ credits.

Test case $4$: You obtain $4$ credits for each of the RTP courses, accounting for $4 \cdot 9 = 36$ credits. You also obtain $2$ credits for each audit course, accounting for $2 \cdot 2 = 4$ credits. Finally, you get $0$ credits for each of the non-RTP courses, accounting for $0 \cdot 4 = 0$ credits. This accounts for a total of $36 + 4 + 0 = 40$ credits.
