P17073 [ICPC 2017 Shenyang R] Little Boxes

Little boxes on the hillside. Little boxes made of ticky-tacky. Little boxes. Little boxes. Little boxes all the same. There are $a$ green boxes, and $b$ pink boxes. And $c$ blue boxes and $d$ yellow boxes. And they are all made out of ticky-tacky. And they all look just the same.

The input has several test cases. The first line contains the integer $t$ ($1 \le t \le 10$) which is the total number of test cases. For each test case, a line contains four non-negative integers $a$, $b$, $c$ and $d$ where $a, b, c, d \le 2^{62}$, numbers of green boxes, pink boxes, blue boxes and yellow boxes.

For each test case, output a line with the total number of boxes.
