Solve the programming task below in a Python markdown code block.
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 ------

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.
