Chef is making a dish that consists of exactly two ingredients. He has four ingredients A, B, C and D with tastiness a, b, c, and d respectively. He can use either A or B as the first ingredient and either C or D as the second ingredient. 

The tastiness of a dish is the sum of tastiness of its ingredients. Find the maximum possible tastiness of the dish that the chef can prepare.

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

- The first line of input will contain a single integer T, denoting the number of test cases.
- The first and only line of each test case contains four space-separated integers a, b, c, and d — the tastiness of the four ingredients.
   
------ Output Format ------ 

For each test case, output on a new line the maximum possible tastiness of the dish that chef can prepare.

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

$1 ≤ T ≤ 100$
$1 ≤ a, b, c, d ≤ 100$

----- Sample Input 1 ------

3 5 6 2
16 15 5 4

----- Sample Output 1 ------

21
----- explanation 1 ------ 
Test case $1$: Chef can prepare a dish with ingredients $B$ and $C$ with a tastiness of $5+6=11$.

Test case $2$: Chef can prepare a dish with ingredients $A$ and $C$ with a tastiness of $16+5=21$.
