Chef has 3 boxes of sizes A, B, and C respectively. He puts the boxes in bags of size D (A ≤ B ≤ C ≤ D). Find the minimum number of bags Chef needs so that he can put each box in a bag. A bag can contain more than one box if the sum of sizes of boxes in the bag does not exceed the size of the bag.

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

- The first line contains T denoting the number of test cases. Then the test cases follow.
- Each test case contains four integers A, B, C, and D on a single line denoting the sizes of the boxes and bags.

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

For each test case, output on a single line the minimum number of bags Chef needs.

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

$1≤ T ≤ 100$
$1 ≤ A ≤ B ≤ C ≤ D ≤ 100$

----- explanation 1 ------ 
Test case $1$:  The sum of sizes of boxes is $2 + 3 + 5 = 10$ which is equal to the size of a bag. Hence Chef can put all three boxes in a single bag.

Test case $2$: Chef can put boxes of size $1$ and $3$ in one bag and box of size $2$ in another bag.

Test case $3$: Chef puts all the boxes in separate bags as there is no way to put more than one box in a single bag.
