Chef decided to redecorate his house, and now needs to decide between two different styles of interior design.

For the first style, tiling the floor will cost X_{1} rupees and painting the walls will cost Y_{1} rupees.

For the second style, tiling the floor will cost X_{2} rupees and painting the walls will cost Y_{2} rupees.

Chef will choose whichever style has the lower total cost. How much will Chef pay for his interior design?

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

- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of a single line of input, containing 4 space-separated integers X_{1}, Y_{1}, X_{2}, Y_{2} as described in the statement.

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

For each test case, output on a new line the amount Chef will pay for interior design.

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

$1 ≤ T ≤ 100$
$1 ≤ X_{1}, Y_{1}, X_{2}, Y_{2} ≤ 100$

----- Sample Input 1 ------ 
4
10 20 9 25
10 20 9 20
10 20 20 10
100 43 85 61

----- Sample Output 1 ------ 
30
29
30
143
----- explanation 1 ------ 
Test case $1$: The first style costs $10 + 20 = 30$ rupees, and the second costs $9 + 25 = 34$ rupees. The first is cheaper, so Chef will pay $30$ rupees.

Test case $2$: The first style costs $10 + 20 = 30$ rupees, and the second costs $9 + 20 = 29$ rupees. The second is cheaper, so Chef will pay $29$ rupees.

Test case $3$: The first style costs $10 + 20 = 30$ rupees, and the second costs $20 + 10 = 30$ rupees. Both styles cost the same, so Chef is always going to pay $30$ rupees.

Test case $4$: The first style costs $100 + 43 = 143$ rupees, and the second costs $85 + 61 = 146$ rupees. The first is cheaper, so Chef will pay $143$ rupees.
